But the Schroedinger equation is parabolic, meaning that it's first
order in time and second order in spatial coordinates, so how would
this substitution help there? Frankly, I don't see the advantage.

The cross product term on the space side is zero for traveling waves.
These can be separated leaving you with two 2nd order differential
equations both set equal to energy.

Cross product term? I'm not even sure what you are saying.

Is this the Schroedinger equation you're talking about?:
