You're correct about the powerplants. I did not make a ship specific reactor and opted to use the fleet standard one combined with a fighter plant instead. The engines are already at their limits of usable fuel efficiency, since my fast tankers use the same ones. So far, speed has been a non issue as every ship except tankers possess PD and my enemies are around 2-3 times slower than the beam fleet. I may use more engine boost in the next generation in combination with fast commercial ships, which detach from the fleet upon encountering contacts.

My next foray into experimentation will be a 10kt stealth cruiser. I have 99% cloak tech and 2% thermal signature engines, giving me a cross section of 100t and thermal signature of both 1650t engines at around 60. What sort of sensors and weapons will keep this stealth? Ideally it won't have to use heavy PD and armor with stealth and speed as its main defense.

This refit included a reduced armament in return for more armor. The active sensor has been refitted and she sports ECM now. These Absolutes have been the mainstay of the fleet; they've destroyed more tonnage in hostile ships than anything else, and none have been destroyed. I'm pretty happy with them. Soon they will become a legacy fleet as my next engine tech arrives and better shields are researched.

If you are planning on combat refueling/resupplying these things, I would suggest you consider possibly refitting the engines with higher power, lower fuel efficiency engines. I think this will give you a significant tactical advantage and will allow you to close the distance to your targets more rapidly, providing fewer opportunities for the enemy to fire on you.

In my experience, the shooting part of combat typically lasts less than a few hours, so I find that long range combat ships are not as useful as short range ships with more powerful engines.

Also, this may be intentional on your part but I will point it out anyway, you have insufficient reactor power to operate all of your weapons simultaneously at maximum firing rate. Reactors aren't that big and it might be worth trading some MSP for more reactors.
Nevermind I didn't notice the 2nd reactor design. However I do believe it would be more spatially efficient to utilize 3x 8 power reactors.

There are a number of different beam ship philosophies.

Parasite battleship/destroyer whatever you call it.  Maximum boost engines, perhaps maximum sized for fuel efficiency.  Speed is king.  No turrets needed.  Against some enemies, the enemies will have reduced accuracy if they haven't turreted their main guns.  They can either hope to win by absolutely outranging the enemy if they have a tech advantage, or by having a shielding advantage, they come into range, fire, and withdraw out of range again and let their shield regenerate.

Sluggers, designed to be fast enough to close with the enemy, and tough enough to survive doing so.  A slugger fleet will incur damage and casualties, but they close to a range bracket where they do more damage than the enemy.  Maybe they have a higher dps, or they have a huge burst from reduced sized lasers that they fire at point blank range.  As they have to close within enemy weapon range, they generally do not have the time for shield regeneration, so shields would be minor compared to armor.  Expect your fleet to be in repairs for a while after the battle, but hey, you get crew grade improvement from taking damage!

Swarm, (no longer as practical with the meson changes), philosophy was that the enemy couldn't split its fire and reliably kill all of them before they did damage.

Beams as support.  You have a couple of beams on all of your capital ships, so as to have the ability to finish the enemy after.  They exist to prevent free kills by the enemy and to save ordnance.

Point defense ships.  In ship to ship combat, they deny the enemy the opportunity to do point blank damage with impugnity.

The Absolute is absolutely a cruiser role.  It can reach almost any point in a typical empire without refueling, and possibly without needing refueling to return.  That is a pretty long range, and comes at the expense of top speed.  If you want a fast responder that can shift to any part of the empire quickly, or can check out the frontier, this can do the job.  Whether it can handle the problem once it gets there is a different question.

It can also serve as forward picket for a substantial period of time.  In VB6, I preferred using carriers for long endurance picket, because the parasite craft could have the speed advantage over any enemy, while having the endurance of the carrier.

I'm currently designing a heavy cruiser and for shields I placed a 750t generator with level 3 regen I think. How much power do shields draw?

They have their own internal power plants. Everything does except beam weapons.

This is probably the closest design I have in my current game, though it's a slightly lower weight class and has a different role, with yours I might be tempted to go with larger shields:

This is supposed to take on more of a bouncer role to protect the carrier fleet, it's supposed to be deployed in reasonably large numbers alongside a smaller corvette design to buy time in case the core fleet becomes threatened. I haven't had to use it in it's intended role yet so I can't tell you how well it functions (though I did use it's fleet group to finish off an ailing spoiler ship whilst taking fire from their STOs). But it's definitely tough enough to take a few hits and get into the fight. It was also specifically designed to do this role in relation to the aformentioned spoilers and their particular ship design so take that for what it's worth. For your ship it probaby makes sense to sacrifice the level of protection I put in for more firepower, but it's an idea.

Well that's the point of this particular cruiser, it can't sustain itself very long outside of laser range so its purpose is to use the mass where a meson could go as more engine power to rapidly close the distance and destroy things from 100,000km or so where those 150mm lasers hit maximum damage.

The problem is that it is too thinly skinned to approach that close against anything with a decent penetration power itself, at least if it is up against something even close to it's own technology level.

I would give at least about 8 levels of armour at this technology level for a ship of this type and at least some shields as a defence against microwaves if those are around.

The weak armour also make you weak against Meson weapons.

Kind of off-topic, but nothing's weak against mesons. After 4,000 research points spent on armor retardation tech, you can build a meson that has a 19% chance of penetrating 5 layers of armor, or put those points into laser focal size and build a laser that has a 100% chance. Dump a cool million research points into armor retardation tech and you can max out your chances at just under 70%.

About the only use case for mesons is if an enemy invests a stupid amount into massive, fast-charging shield generators and no armor.

You will have to approach rather close for most lasers to penetrate the armour though. A Meson could do that at a much greater distance and safety.

You most likely are not going to use Meson beams as the only weapon either if you have them.

I see it as having a role similar to Gauss Canons as secondary weapons, more to maim than to kill, allowing for boarding actions and etc. make some holes with the lasers, slow it down with some mesons, so you dont need to mind the shields, and then land your marines.
but then again, by this point you might as well just keep the shields down with some fire, and blast it with gauss untill your marines can get in safely so...

Your long-range beam fire controls have only three-quarters the tracking speed of your lasers, while the short-range beam fire controls have five-quarters the tracking speed of your gauss turrets.  Having a better fire control than your current weapons can be a useful way to build in upgrade potential, but with the split you're definitely wasting resources on at least one of them.
