that's really good to know b/c they don't normally list those dimensions in the description. probably a good practice to just message the store to confirm.
I'm starting lean towards 3 bolt direct mount cranksets with 2 pinch bolt non-drive crank arms. They have both chainring/power meter flexibility, while being compatible with different size bottom brackets.
Like for example T47 has several variations with 68mm external cups, 86.5mm internal cups, and 78-79mm internal/external cups for bottom brackets! That's not including variations in 24mm/29mm/30mm spindle diameters. I guess the actual interface is now standardized, but under that standard are a plethora of different sizes.
