My wife introduced me to Star Trek about 5 years ago now, and it's still our favorite thing to watch together! We've watched through almost everything together, and it's been the best way to enjoy Trek!
We always try to watch new episodes the evening they drop, so we're really looking forward to SNW S2! 🥳
Everything is a lot of Star Trek! (but you should really watch everything eventually) I recommend tackling it one series at a time, and it will go by faster than you'd think,
My wife and I started with Star Trek: The Next Generation (TNG) and I think it is a great place to start!
After that you could watch Star Trek: Voyager (VOY) or Star Trek: Deep Space Nine (DS9). DS9 being one of my favorite pieces of media ever. I love it so much. 🥲
Or if you want something more modern you can start with Star Trek: Strange New Worlds (SNW). The second season airs in a few weeks, and I hope it's just as amazing as the first season!
