Some food for thought
TEC has the most focus on hull of all 3 races, and they have the best armor tech. Advent and Vasari are more likely to put resources into shield techs, which don't benefit strikecraft at all.
Vasari fighters get no damage upgrades
at all until NME warheads, which only goes up to 20%. The phase shield skips arn't very useful unless you go Subverters, or in support of Evacuators. (Ideally both.)
TEC gets antimatter restoration in culture, which is awesomely useful for light carriers. Advent get their antimatter caster, but it's rarely used; I don't even know if it works on frigates.
Perchirons are the toughest light carrier by a larger-than-usual margin.
The Vasari are most likely to research up the Phase Missiles, Waves, Armor, Hulls, and Antimatter tech lines.
The Advent are most likely to research up the Lasers, Beams, Shields, Hulls and Antimatter tech lines.
The TEC would research up the Autocannons, Missiles, Armor, Hulls, and Shields tech lines.
I don't know what kind of weapon TEC and Advent fighters use, so here are what bonuses their
bombers get:
Vasari:
Better hull.
Tougher armor.
Stronger phase missiles.
Higher chance to penetrate shields.
Advent:
Better hull.
Stronger beam weapons.
TEC:
Better hull.
Tougher armor.
Stronger missiles.

Now for fighters.
If TEC fighters use lasers, then they would have to research up that line too. Although TEC laser techs are not really expensive, they are also however primitive, and the TEC would end up with the weakest fighter squadrons anyway. If the TEC fighters use Autocannons or Missiles, then they'd get full bonuses.
If Advent fighters use Plasma weapons, then the Advent would either have to research up their expensive Plasma weapons line for little returns, or end up with weak paper-plane fighters that, while numerous, would get shot down like flies in a cyclone. If they use laser weapons, then they would have a decent weapon, but they would still be unarmored and would be swatted by enemy flak/fighters.
Vasari fighters use Phase Missiles(I know this much), and they would get boosts to all aspects along with the rest of the Vasari armada, so no extra research. They'd end up with the strongest but fewest fighters, but their four-plane squads would be able achieve high kills-to-losses ratios unless their opponent micromanages(in which case their user can micromanage as well).
__________________________
So the Advent fighters, being numerous but lighter, are akin to point interceptors. They can shoot bombers/siege/scouts/LRMs effectively but are vulnerable to enemy fighters and flak.
The Vasari fighters, being few but tougher, are akin to dogfighters. They can kill enemy fighters and shoot bombers/scouts/etc. while not being too badly affected by flak, but they can't be everywhere at once.
The TEC fighters are somewhere in between. They would intercept better than the Vasari equivs and dogfight better than the Advent equivs, but wouldn't be the best at either.
