My vote is a GRX 48-31 crank with the 11-36, maybe an 11-40 if really necessary.

A 48:11 should be enough for a lower cadence at a higher speed.

I would think 31:36, or 40, should be low enough.

There really isn’t an issue with spinning in the 31:36/40 as I’m sure there are a lot more gears available to prevent high cadence.

Edit added: There is a possibility that the 31 is so low that it will be necessary to shift between chainrings a lot more if the current 36 is the primary ring being used.
