Obviously a vast amount of characters to cover, so maybe a bit-by-bit approach for the ones that had some more screen time would be interesting to see their portrayal. The Russo Brothers/cast have been developing everything so there might be deviations from the usual or former character typings (we've had Thor as SLE at some point etc), plus we see more in-depth arcs.
Thanos — SX-last, valuing, I typed him LSI for Infinity War and it might still be a good fit
Cap — SOC/SX
Thor — SF 9 (desintegrated from 3w2?) possibly SOC last
Tony — /
Marvel — 8
Nat — Logics 6
Clint — SOC
Banner — Intuitive
Rocket — ENTx, still 7w8 or 8w7-ish
Wong — Logics 5w6
Rhodey — Intro?
Pep — ESI
Ebony Maw — ILI 6
Ant Man — SEI (Paul Rudd plays himself)
Nebula — 8
Okoye — Beta ST 1w2
Valkyrie — ST?
