My research thus far indicates that the idea of circular orbits for the Sun and the Earth in the copernican model have been ruled out.
Well you see that isn't the issue.
The issue is whether relativity undermines itself by making a stationary Earth equivalent to an orbiting Earth, as you claimed. It does not. And the reason is that an orbiting Earth is accelerating, and therefore a frame of reference that takes the Earth as stationary cannot be equivalent because of that acceleration.
