Speaking as someone who JUST got back into the hobby after a very long time and might as well have been new to be perfectly honest... DnD 5e is fairly accessible, but it's worked to get me back into the hobby and it's worked to help my wife to get into it for the first time, so maybe try looking for a DnD 5e game to play? I would also suggest maybe doing a little research into a couple different games first. You don't have it immerse yourself in lore but maybe just see if you can get some basic rules from online tutorials or YouTube videos, maybe pick a system you like if you find that 5e isn't working, then when you feel like you have some better idea of the specifics of what you want, post that you're looking for a specific game. My gut feeling is that people will be more likely to take you on if you have a specific interest in what they are doing as opposed to a vague interest in RPGs overall, if that makes sense.
