Well, as BobFace state just up here scatter gun (both balistica and energy) are preatty powerful, but you have to be very close to the target and they are not automatic weapons this mean you need to release and pull the trigger again for shooting.
That makes them good weapon for the "boom and shoot" tactics (fly toward the target and shoot while passing over), so ideal, in my opioni, only while equipped in really fast an manuvrable ships or while facing big slow target... so any situation where you are a lot more agile then your target.
Blistic gatling are very good weapon and if overclocked they besicaly spit an uninterrupted stream of fire... and chew trough the ammo accordingly.
Laser repeater are good also, especially the Hurston one that I found a bit more accurate and consistant in the shot spread...
If you prefer single shot weapon instear of repeater I think Tarantula series are the go to balistic weapon, especially if overclocked they keep a good rate of fire and have a large ammo pack
Can't provide suggestion on laser cannon sicne I'm not in love with them: form my point of view theose are good only on lager scale where you can 1-shot a target, if you need to use them for dogfight then, the output is not good enought to get ride of the shield and do damage in a reasonable time frame. But of curse this is an evalation based on my precision so I suggest to try them out.
Also ans specifically for the Hawk: remember the hard point are fixed as stock: so if you want a gimbal configuration you have to mount 2x S1 gimbal mount and 4xS2 gimbal mount and lower all the weapon on S1. Never try it but my feel are that this configuration will drop damage output a bit to much.
Also, since there are so many weapon on fixed mount try to use 6x of the same weapon type, so 6x laser repeater, or 6x cannon for example, this way you'll have single pip.
