Crank/bottom bracket Compatibility Question

Can somebody please help me sort through crank/BB compatibility?

I have a 2023 Grizl 6. I am trying to replace my recalled FSA crankset with Shimano GRX, as other people seem to have done without issue. But I cannot make any sense at all of the various BB standards. Canyon says my frame BB standard is PF86.5 and I have a Token Ninja Lite BB4124 bottom bracket. I'm trying to figure out if that's compatible with either the Shimano FC-RX600-10 or the FC-RX810-2 cranksets. The spindle diameter is the same, by spec and confirmed by measurement. Is it just a matter of spacing the crank arm off the BB the right amount?
