Solar bulge would be a standing wave but small and vary with the distance from the sun.
That's a different effect, in a different plane. The equatorial bulge is the bulge around the equator in the plane of the Earth's rotation about its axis, which is tilted from the plane of the Earth's rotation about the sun by around 23 degrees.
The tidal effect due to the sun is not the equatorial bulge and I don't think it's a standing wave either.
