This is actually the first time I used the frontier, not before changing everything though. Really I have just always stuck with particle beam weapons and normally two sets of turrets for easy fighting. Then I started trying ship boarding and was killing a lot of ships I wanted to capture. So swapped in EM weapons, reducing damage dealing as a trade out.
Since I wanted to go do the Battleship Calmulus and I wanted to try the pulse laser turret, this was setup with Laser turrets, missiles and my standard four nose mounted particle beam weapons. Laser turrets didn't do enough damage, I have no skill point in them and missiles where to infrequently available to be fired, I don't even start acquiring target until 2KM even though the range for them is 4K+, so I dropped them too.
Now I have three different class-c ships, spend some credits testing weapons to see what works the wat I needed, this setup work well for heavy DPS on a target and it has been proven to also be able to capture a ship, just a little trickier. Have to take the power away from the turrets before they kill a target you are trying to capture, then target the engines and slowly do a hit at a time to work the health down to a dock prompt. I am getting better at that so I might just drop the EM weapons from my other ships too for more burn it down DPS. Likely not turrets though, they just have poor aesthetics and really make a ships profile look crappy.
