Hc32f460 MCU Clock Speed Issue/Bug

I guess it is possible that 168MHz is the proper freq, where everything runs at the correct speed, while 200MHz makes everything run slower and that’s why everything sounds healthier, as the printer hardware can handle those physical speeds created by the 200MHz MCU clock.

FWIW, I do not think this is the case.
Regardless if 200 or 168 both are fast enough to drive your speeds and if more steps than available processing power are generated, then Klipper reacts with Rescheduled timer in the past

(shouldn’t a higher clock speed produce higher physical stepper motor speeds?)

This would be a catastrophe. The steps and their timing must never relate to the the MCU freq. The total number of steps over all steppers depend on the processing power / clock speed.
You would not want your steppers run 4x faster on 200MHz board compared to a 50MHz board.
