Yes, if gear range (chain ring wise and cassette size) allows for the some gain ratio with the different crank lengths, they maintain the same cadence at a given power across different crank lengths. gear range is the only confounding variable and pretty easy to address: need easier gears when going to shorter cranks, harder gears when going to longer cranks. I’ve seen pros have pretty locked in cadences.
If this is true, then they're altering pedal velocity to maintain cadence. You can't hold the same cadence across different crank lengths without changing pedal velocity. This will, of course, result in changes in the muscle force/shortening velocity relationship.
Yes, zero argument there: pedal/angular velocity increases with longer cranks if cadence is maintained, and there are definitely biomechanical and metabolic changes related to changing crank length in addition to % muscle recruitment (quad vs glute engagement). That doesn’t negate the hypothesis in the OP.
I am strongly suggesting that % muscle recruitment + % mass over the pedals is more consequential/important than other biomechanical and metabolic changes related to changing crank length.
