A lot of the mods seem to like adding variance without much extra decision making. Some of the ship mods can be interesting though, as long as they're not super strong.
With your setup I wouldn't buy IB1 either, definitely just fish for systems over weapons 8. Usually purchase preference is shields 2 > good systems > weapons > augments > crew, though some ships have exceptions. If your weapons are able to consistently break enemy's ability to damage you then support systems are the most useful pickups. Especially because picking up systems early depollutes the pool in the future, so you have more chances of getting what you want (battery in particular is a good purchase for this reason).
I'd imagine hacked shields --> halberd piloting/shields/missiles would be the way to go with mind control vs flagship and your weapons. Halberd doing damage to piloting + MC would set evasion to 0 until another crew goes in there, which will take time with hacked shields door block. Between halberd and hull laser you'd have 4 damage on missiles to break them with door block from shields towards that too. Flak can just be thrown on shields so that they take 5 damage (halberd + flak), leaving 2 layers, clumped enemies, and a lot of chaos.
With some other setups I do indeed prefer to hack piloting since MC can't guarantee 0 evasion w/o halberd beam and can still be used to block repairs on missiles. With cloaking + hacking I nearly always hack missiles because the ability to completely ignore that system changes the dynamic of the RFS fight so much.
