I'd suggest DME (
Dassault-Mikoyan Engineering) as a good fighter-heavy mod faction. They've got some good ships that aren't carriers, but they also have top-of-the-line carriers, strong fighters, and two capital-class combat carriers: The Zelenograd is a battlecruiser type ship with only two fighter bays - but its fighter recall system lets it make devastating use of bombers. And the Jeanne d'Arc is just a straight-up combat carrier, with six wings of fighters and direct firepower that's (arguably) comparable to a Legion.
Alternatively, I'd also suggest
Sylphon Research and Design. As a faction, they're not very fighter focused overall, but they've got a decent variety of strong drone fighters, as well as several dedicated drone-carrier hulls; the capital one is particularly fun to play with, as it has a unique take on variable weapon mounts: a pair of large energy slots that, when left empty, turn into extra fighter bays. (Personally, I hate losing crew, so I'm definitely fond of zero-crew fighters when I can find ones that are worth using.)
