My thoughts on fighter doctrine are to use them well in advance of the fleet. My standard fleet speed is 6 kkps. The fleet pops in through the wormhole, AWACS detects enemy ships at extreme range (2-3 billion kilometers), the decoy fleet(heavily armored and shielded BIG ships loosely based on Blue Emu's "Rocks") heads directly for the hostiles with their active sensors lit up, ~6 hours later the fleet heads in the same direction, at 500 million to 1 billion km the fighters are deployed, at 200 million km the CAs launch an alpha strike by which time the fighters should have already closed to their combat ranges and they launch a TOT(Time on Target) strike to coincide with the CA missile arrival. Beam armed CLs and Gauss armed FFs clean up stragglers. The CVs and the CC(command cruiser, my AWACS) stay farthest back covered by Gauss PD DDs and FFs. I do still have some AMM armed PD DDs and FFs, but they are being phased out in favor of Gauss CIWS and PD.
Anyway, here is a slightly revamped F-15:
