There is no clear answer to that, your path is built on your determination, languages are just a starting point.
It just depends on what you want to do. It's okay if you cannot answer that question but you cannot expect others to do so. We all have opinions about "what we would do" or "which language sucks". But that's not helpful is it?
Maybe you want to try a little bit of python? for computer models rust? for IOT go and or node.
Besides that, focus on doing it right, try to write tests, search hashnode for the classic book suggestions.
You just started your journey :) by increasing our knowlege we increase the circumference of things we don't know.
