Brave Bird is a must. Close Combat for coverage against Rock, Steel, and Ice. And definitely U-Turn so it can pivot after lowering its stats with CC or its HP after BB, and come back later with another Intimidate.
For the Normal STAB, well, since Return doesn't exist anymore, and Double-Edge is an egg move, there isn't really a good Normal STAB for Staraptor without breeding (except maybe Giga Impact). Maybe Quick Attack or Facade for a safer Staraptor but it won't hit as hard.
Aerial Ace is situational but it could potentially work against Flint's Infernape, if Drifblim uses Minimize + Baton Pass switch on it. Defog can also help to shut down Lucian's Mr. Mime walls.
