Rh8 seems obvious because we attack the weak h5 pawn
so Rh8 Kh4 Be8 even if Be8 makes us lose the f5 pawn we can gain it back with Bxh5 we traded a f pawn for the h pawn. this would generaly be weaker but because of the strong discovered attack white have we gain a tempo because he needs to move his king out of the discovery. then we can play Bd1 and the c2 pawn or f pawn falls either after Ne1 Re8 or Nb4 h5

I'm with Glenni on this one, Attack the h pawn, lose the f pawn and put black's bishop to d1. White cannot defend their chain of pawns against the bishop at d1
