The fundamental theories of modern physics: GR and the standard model of
particle physics.

You got that backwards.

Not at all.

Somewhat. Due to English language nuances, not anything related to physics.

"absolute" in the sense that a frame is unique, has no interest. Any
frame has that property.

"absolute" in the sense that the laws of physics are different in one
frame than in any other is not part of modern physics. The ancient
aether theories had it, but they have all been refuted experimentally.
Your example here does not go deep enough.

I have no "concept of absolute reference". <shrug>

Yes. That is the PoR. As I said.

Yes. Even after many glances no connection appears. Some people around
here _dream_ of a connection....
