I'd love to know how to dance, I mean really properly dance for every situation, not just a generic two foot shuffle. I've seen some people who can dance properly and they looked cool as fuck.

Probably the ability to not be an unbalanced idiot 24/7. I literally fell up the stairs twice this week. There are few people who are less scatter-brained than me.

My first thought was also languages, but all the classes for a bachelors in nuclear engineering would be nice. Huge passion of mine and I can't really pursue a degree at this point in my life

maths.

I never had enough brains to not suck at maths.

How to fluently speak a foreign language. I'm A2 with French but I could live with Spanish or German as well.

I did Brazilian Jiu Jitsu for a while untill after the 3rd injury I realised this isn't going to be good on the long run and I stopped doing it. However, it was long enough to see what a magical power that is so I'd say that being able to posses the skills of a black belt without going thru the training would be quite nice.

People don't realise how helpless you'll feel trying to wrestle with someone who knows what they're doing. Being bigger and stronger will not save you unless you get really lucky.

Time travel

being able to inspect/ appraise any item and get comprehensive details about it.

it would be great to spot antiques and famous works from garage/ lawn sales.

If I had that technology, I would upload everything available on file. The common fictional notion that you could "fill up" your brain is wrong.
