If you're familiar with TNG and the subsequent movies, then you already know just about everything you need to start with Picard. There are a couple references to the first Trek reboot movie from 2009, but other than that the series doesn't really rely on DS9 or Voyager.

Discovery makes some TOS references, the most important of which is Christopher Pike, but if you're familiar with TOS you should be fine.

As for Lower Decks, I haven't watched much of it, but I had the sense they relied on a lot of fast-paced in-jokes, so that one might be more difficult to jump into.
