As it is, all large weapons are kinetic analogues and don’t synergise well with energy weapons. Even the “Large Energy weapon”, aka Fighters, bypasses shields, causing a split in the damage dealt. We need an energy weapon that can contribute its firepower to other energy weapons like Plasma Cannons and Armourbanes to bring down shields quickly so all the other weapons can work their magic on the hull instead of having half the damage hit the hull while the other half drains the shields without bringing it down.
Some Heavy Plasma Cannons or Energy Torpedoes should do the trick.
Another possible weapons suggestion would be Kinetic guns that do shield damage. They would alleviate the need for a lot of generators on a ship and can mix well with armourbanes so ships can use the “free” energy from the engines for energy weapons then use ammo based weapons once that is used up instead of being forced to go 100% energy or 100% kinetic.
Not sure if the reverse is a good idea though, an energy weapon that can ignore shields is like a weapon with all the advantages (infinite ammo, shield piercing) and none of the downsides, but IMO there is a niche for kinetic weapons that can hit shields as partners to energy weapons.
