Rook to H7, pawn to f7?

No because Rh7 Qb2#, Black wins.

Pawn to f7, rook to h8.

f7+ Kf8. o̶u̶t̶ ̶o̶f̶ ̶c̶h̶e̶c̶k̶m̶a̶t̶e̶ ̶s̶e̶q̶u̶e̶n̶c̶e̶ ̶e̶i̶t̶h̶e̶r̶ ̶w̶a̶y̶.̶ longer checkmate sequence, miscalculated here.

OK, here's the solution:

Rh8+ forces Kxh8 (all other fields are defended by White, this is the only move King has left. the additional reason you have to put pressure on opponent is that Black has the abovementioned checkmate in one waiting.)

f6# (h7 and g8 are defended by pawns, Bishop puts the check, Black has no way to hide or capture)

What's happening here is called deflection: you sacrifice a piece but force the opponent to a disadvantageous position.
