Answer 1

Gravity, where it’s strong enough, does counteract cosmic expansion.

So there’s no expansion within galaxies, or within sufficiently massive galaxy clusters.

Not yet. Or at least possibly not yet. There are a few possible scenarios, and one of the them is the Big Rip, where expansion keeps accelerating until it does so exponentially, in which case there would cone a breaking point where in a short amount of time, galaxies, star systems, planets, molecules and finally atoms themselves are literally ripped apart.
