Given the amount of change I would recommend doing this as two separate PRs.

Before dropping 3.9 I would recommend bumping ruff, we are on a very old version, and new versions should have better / more robust auto fixes.

I am not sure what the purpose of doing this before 3.9 is. If we drop 3.9 we should get better rule system because it does not consider py3.9 specific things.

This is specifically talking about UP rules.

Oh, weirdly the UP rules are not activated in our ruff configuration so you're right that it is not needed to upgrade ruff before dropping 3.9.
