Look, it's not that hard and as a CA you should know how long it will take you to taxi to the gate. Shut it down after cool down and wait to start the APU until you get within throwing distance to the gate. It spins up so quick it will be up and running by the time you set the brake.
The question wasn't asked from the point of view of someone who's never flown a plane. On the 145, we shut down number 1 on the way in. Curious as to why shutting down number 2 is SOP on the 175.
