Your degree of prior knowledge isn’t much of an issue. Every show explores its own little corner of the universe, and they all stand well enough on their own.

I’ll make an exception for Lower Decks - it’s full of referential humour that you’ll appreciate more if you’ve at least seen TNG first.

I’d say start from the beginning, unless you’re particularly uncomfortable with TV from the sixties. Most Star Trek takes a season or three to really find their groove, but TOS fires on all cylinders right out of the gate.

If you crave something more modern, Strange New Worlds is an excellent place to start, with the advantage that you can enjoy new episodes as season 3 comes out later this year.

TNG is a popular recommendation, but it’s a little dated itself, and the first season is strikingly rough around the edges.
