Obviously theoretical but if I took a light year long stick and say pushed a button at the other end would that button be pushed at the same time for me as say someone standing at the button? How does the frame of reference work when physically moving something? And could that “work” as a method of instant communication?

No. The molecules in the stick will propagate a force towards the direction you pushed. And although the molecules move practically instantaneously to our senses, it’s still not as fast as light, and light is nowhere near instantaneous.
