I have a current gen Crux as my N=1 road/gravel setup (I now have N>1 mountain bikes, though) and use 35mm deep x 25mm internal wide rims with 38-40mm tires for gravel, and 46mm deep x 21.5mm internal wide rims with 30mm tires for road. Truthfully if there were no tires on either set of wheels I would need to look hard to notice the depth difference. Both work wonderfully for their main purpose, but both would be pretty great at both purposes if pressed.
Mid-30s depth is pretty great in carbon for a mix of building a strong stiff wheel and still being light for a strong rec rider of your size. I'd go 25ish for the internal on the new wheels.
Do yourself a favor and get some rotor shims and standardize your calipers and rotors on all wheel/bike combos and never worry about switching again.
