Re Boeing “gear down, flap XX” from memory there’s a priority valve in the flap power control package that gives priority to the gear should the pressure drop below 2000psi, with two hydraulic pumps running this likely never occurs. With one then you may notice the flaps moving slower / stopping until the gear is down and locked and the pressure returns adequately to run the flaps.
