If you like MMOs or Star Wars even a little bit, I recommend at least giving this game a shot. Free to play players can do a fair bit compared to some other MMOs out there, but think of it as an extended free trial. There's definitely enough content there, though, for you to try out as F2P to get a solid idea of if you want to continue playing and sub at that time or not. You can level to 60 as a F2P player, though there are some restrictions (mostly to combat things like gold sellers). There is also a third status called "preferred" which allows you access to all expansions as long as you sub for one month (to be clear, you keep the expansions even if you unsub), though this does still have a few restrictions compared to an active subscriber.

In terms of actual gameplay, though, the combat is your typical tab target MMO combat, but the mix between blasters and sabers is fun and the abilities are pretty cool as well. The environments are really detailed and diverse, and the graphics aren't bad at all for a 12+ year old game. There are 8 unique origin stories (think classes) to experience, all of which are voice acted, and the group content is pretty fun too both for PvE and PvP. Galactic Starfighter, which is the ship PvP mode, is rather outdated, but people do still play it. You'll likely get dominated if you do, though. I've tried it a few times, and it wasn't for me, but it does exist so I wanted to mention it. There's also player housing, which is always a nice thing to have in MMOs.

Even if you just play it for a weekend to get a feel of whether or not you think you'll like the game, I recommend doing so. It's a good time, and the community is quite helpful and welcoming, which seems to be hit or miss in MMOs these days.
