Aug 22, 2022 at 20:30 comment added Wojowu You may want to assume $Z$ is closed, as otherwise a countable dense subset of $S^2$ will be a counterexample. Also, I don't see why you have split this question into two parts, it seems to me like the other part would be perfectly fine as a paragraph in this question.
