Default Whether the square wave controller is suitable for high-speed motor

Compared with the square wave controller, FOC is technically advanced, but is it really suitable for the high-speed motor control application of UAV propeller?
Personally, I think FOC is more suitable for low-speed servo control to achieve accurate position and speed control. Small torque pulsation.
1. And for high-speed operation, whether to consider the problem that the maximum speed is limited by PWM switch frequency ~
2. What is the main consideration of adopting FOC scheme for UAV propeller control? Speed smoothness?
3. FOC is undoubtedly a better solution for low-speed work such as cradle head.
Hope everybody discusses!
