Contrary to how you might think PD = effective against missiles = effective against fighters, I find less PD can actually be more effective against fighters at times, because certain wings like the broadsword can clog up your PD with those active flares while being very dangerous to your shield, thus leaving them untouchable and yourself open to enemy strikes. I have had great experiences with both a SO hammerhead and a SO eagle for less PD and highly aggressive behaviour and just bulldozing everything (granted I used them as flagships though).
Hammerhead: 2x heavy machine guns, 2x light assault guns up front, 2x LR PD lasers at back. Missile slots empty. SO as mentioned.
Eagle: 2x heavy machine guns (leave the middle ballistic empty), 1x ion cannon in the front middle small energy slot, 2x IR pulse lasers, 3x pulse lasers, 2x burst PD at the back. Missile slots empty again.
For the Eagle I initially tried a PD heavy approach but it just couldn't kill fighters fast enough. After a few rounds of optimization I came up with the above. It can do it all, it has the grunt to take out fighters quickly, and that same firepower is pretty deadly against your regular ships. You might think it's open to missile attacks but unless you're getting completely swarmed you can usually swing the HMGs around thanks to maneouvering jets (also helps if you want to speed up clearing off fighter swarms). The burst PD is almost always enough to get rid of those annoying salamanders with precision and not an enormous OP cost since you're only using 2 of them. I guess the whole thing is pretty flux heavy but since you have SO your flux dissipation is doubled and maxing vents helps a lot.
