His passing is "mediocre", but he's still one of the best crossers around. It's always been an underrated quality of his IMO, and one of the reasons why he and Rooney linked up so well when he was still here.
With the way he takes care of his body, he'll definitely keep well into his 30s. He may not become Scholes (what is the fascination/obsession with moving central on here anyways?) but his first touch, off the ball movement, intelligence, and his steadily increasing experience means he can play as an orthodox striker, either side of one in a 4-3-3, or a withdrawn role. Who knows, he may improve on his passing as well, plenty of time for that.
