I would say that what-goes-around-what depends on how you look at it.

One might still say that everything else moves relative to a stationary earth.

You can still use the earth as the center of the universe, IIRC didn't Einstein use that as a reference for relativity?

In classical mechanics though the Earth going round the Sun is not a truth. It is just more convenient for the math. A lot of people forget that.

You can use the Earth as your frame of reference. In fact, one of my orbit classes at NASA did exactly that. We used the Earth as a frame of reference instead of the sun when we described the celestial sphere. (It described the Sun orbiting the Earth in that reference frame.)
