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?

It would have to have no flexibility at all, for it to work as quickly as possible.
Otherwise, if you look at a slow-motion video of an arrow being fired from a bow, you’ll notice that the arrow bends, and with the light-years long stick, you’d have the same effect.
