I've obviously misunderstood this, but yes, agree completely.
OP; you need to buy whatever Rotor crankset you want and then buy the compatible BB from them. Rotor 3D are a 24mm diameter axle whereas Rotor 3D plus are a 30mm diameter axle. Either can fit your frameset with the right BB fitted. It couldn't be simpler.
I ride a bike. Doesn't make me green or a tree hugger. I drive a car too.

3D+ requires a 30mm pressfit

Other companies do the 24mm pressfit - Shimano obviously, and Enduro , KCNC?, Hope, Wheels Mfg...
The 30mm pressfit is rarer and of the top off my head I only know Rotor to do it.
