It could be designed as a support ship. Those 2 large energies could be intended for paladins, which not only protect the ship itself but can shoot over allies to protect them as well. It could still use those slots for offensive weapons, but if it's not a battlecarrier it wouldn't have the stats to go toe-to-toe with other capitals. Another way to encourage paladins would be giving the large energies very wide firing arcs, then have a few medium ballistic hardpoints (offer some offensive power but as hardpoints can't really be used for pd), and like 4 small energy turrets with smaller arcs that only cover the sides of the ship.
In a similar vein, the fighters launched are not just for chasing down frigates (although they would still be good at that), but rather are for supporting your other ships and the carrier's system could reflect that. Maybe it significantly increases the range of non-missile weapons on fighters, but that by itself would probably not be strong enough as a system.
If you want to get spicy you could give it a hullmod that allows it to send support fighters to escort friendly ships. Maybe it increases their roam range but they can only shoot when close enough to a friendly ship so they can link up to its data feed for targeting.
