Anaconda (and the whole "Big Three") is total shit without engineering. G5 Thrusters is a must, otherwise you will suffer. Also, unengineered shields have very poor protection. Unlocking engineers is a fun activity, do not be afraid.
Type-9 can fit 720t cargo, like Imperial Cutter, but Cutter have better overall jump range and also need to be unlocked.
For 80mil you can A-class FDL, for 100mil or a bit more try Chieftain/Challenger/Crusader or Krait Mk II.
