I use the Pinnace designation for jump capable fighters that are used to probe new systems.
Survey Support Carrier is a small carrier designed to support survey operations with scouts and the capacity to drop (commercial) recon satellites. It either has its own jump drive or is paired with a survey tender.
I had a fun class made possible only by salvaged components. The 1000 ton Hunter class. Salvaged beam fire control, salvaged 8 HS laser weapon. Max boosted engine that was about 10% faster than the enemy beam parasite craft, and it outranged them significantly. The Nimrod and the Rexxar took out roughly 20 times their mass without a casualty.
Had a number of beam parasite craft designs. Philosophy was to run the enemy out of missiles, then use the Hunters to take out their empty missile ships. Had some bean counters in charge of ordnance who wanted to use the minimum number of missiles to win, so missiles were reserved for those enemy beam ships that were a threat to my Hunters.
For a while in my empire, no armed ship had active sensors. At first it was pure efficiency considerations, and then it became an anti-mutiny RP thing. No single ship could pose any kind of threat by rebelling. Then there was no armed ship that had active sensors would have its own jump drive. But there was one ship class that had active sensor (capability) and its own jump drive.
The Lion Poker recon fighter. It had a single reduced sized launcher, 2 HS for magazines, and it launched slow but very long ranged recon missiles with either active or passive sensors at planets with suspected enemy or spoiler bases. Because the recon missiles included active sensors, it technically could launch the recon missile at a colony and then use regular missiles to target said colony. But it was the only ship even theoretically capable of independent piracy.
