Yep, compaction is done automatically, but you should run a regular repair

To answer the question, "Yes" compaction needs to run on all nodes.

The right answer, is that you shouldn't be the one running compaction. Cassandra is almost always capable of figuring out when to run compaction on its own, and you should not need to invoke it manually.

In fact, once you run compaction manually, the odds of compaction happening organically in the future are minuscule, so then you're stuck having to do it manually.
