Capacitors on the pcb (close to FET's) are meant for copper traces overload. (Need to be EE or better guru to get it)

Capacitors on the power leads are for poor connectors.

And none of them are meant to provide currents to power the motor, they are here for ESC.

Capacitor size is also a problem, due to the inductance. The smaller the cap (current loop) the better, but you still need to select it for the job. In that respect shorter wider caps are better, but check datasheet as well, not the price tag.
(Avoid long leads on the caps.)
