A standing wave requires a relative motion of the medium at the same velocity of the wave
I think so.
The progressive wave has to meet its own reflected wave. So both have same amplitude, wavelength. Hence standing waves become possible.
interference between the incoming and reflected waves of the same frequency
No. Otherwise it is no standing wave.
By examining a standing wave you can observe the frequency, wavelength, wave speed, and amplitude of the wave.

a standing wave.
When an incoming wave combines with a reflected wave in such a way that the combined wave appears to be standing still the result is a standing still wave.
