Does it only do this when the car is moving, or does it "dance" when sitting still?

It when moving, that would point to an intermittent ground or loose wire somewhere.

If it does it while sitting, and an ohmmeter between the post on the sender (while it's still in the tank) and a good body ground is stable (not dancing) then I would suspect it's the gauge itself. Some heating up and cooling down inside.

I'd pull the cluster and do the tests from the gauge side as that will help diagnose any issue in the wire between the gauge and the sender as well.
