Welcome on in
All you gotta do is explore and try things. Find your style and then you get to build on that.
There is a guide or a video or threads about pretty much everything as you get questions or curious here or there. Discord stuff, twitch stuff, it's all around.
You don't have to do anything so it'll all be there when you get to that stage. You're piratically finding your immersion right now, that's all you gotta do, play, explore, encounter, try different stuff.
Be you, embrace your piratical individuality and preferences. You won't regret that even if it feels overwhelming right now.
One session at a time, be present in the session, goals but not obligations, find rewarding stuff but don't set bars based on what others do or how they play.
Something to remember is that you are never bad at the game, because the game is adventure. You'll sink and lose and get frustrated, never makes you bad at adventure, ever. We are all just trying to have a good time based on our individual preferences, day 1 or first day it doesn't matter, don't let anyone get ya down or discourage you as you figure it all out.
I sink, you sink, we all sink. Get experimental with it, experience is worth more than gold.
