Specifically, there's two key points I'm considering:
Learning more tech: most of the work I did so far was web, Python backend + quite basic JS frontends. I've been contemplating learning kotlin for android, some ML or learning something low-level (that didn't sound very intimidating though). What will I benefit from the most?
Getting a part-time job/internship, something I can do whole studying, to get a sense of reality and some money. I'm not aspiring to be an entrepreneur (yet), none of my projects were built with a business model in mind at all. Where should I look? Linkedin shows mostly stuff for graduates/etc. What pay should I expect (i have absolutely no idea)? Is remote a bad idea?

I'd start by reading. That's it. Just reading and thinking.
