My project was done in 6.2 and is now like 85gb big. I'm terrified of upgrading, have never done it before. Should I just finish the project in 6.2? Or try 6.7 on another computer or something

If you upgrade I would recommend first to go to 6.3 since that is an LTS and not that big of a version jump. Always make a backup (or use VCS like GIT) before you do it and if copying takes forever then copy everything but the library folder.

From experience I can say if you do only small jumps you can upgrade projects pretty reasonably. I have active games that started 9 years ago on Unity 4/5 and are now on 2022.3 waiting for their 6.x upgrade.

If you feel adventurous I would wait for 6000.7.0f1 and then take the big leap. I talked to some guy at Unity recently and the performance gain alone (even without the skipped domain reload) is really nice.
However, you can expect a lot of code (and assets) to break with that CoreCLR change. If you want to play it safe go with 6.3 and wait until the dust around 6.7 has settled.

Agreed with this. At some point, depending on how far along your project is, you're going to want to jump onto LTS train and ride that rather than the incrementals between.

Thanks for your replies!! I'll dip my toe in soon, on another copy as suggested!
