I'd suggest you make a spreadsheet with as many job postings on programming that are near you as you can find (this shouldn't take longer than an afternoon), and learn the most listed language if all you want is to get an entry-level job

if you want to get better and better, you should keep learning other languages (1 every 1 or 2 years should be good enough), knowing 1 language in every paradigm will get you to think about what is possible in other languages, and satisfaction of knowing something new :P

I personally would recommend Python + C to get something high level that can get you to be productive fast, and something that makes you understand that goes into making that at a lower level (without going as low as Assembly), and I think both are good options because they're pretty much here to stay (you might hear some say that you should focus on more modern stuff than C, but there's a pretty good reason it's still here, it works, and it is fast)

and then learning stuff that'll feel weird, LISP, and Prolog, (if you go with this suggestion, when you "finish", you should be 4~6 years in, so try to learn other stuff along the way, like SQL, shell scripting, fundamentals of files and processes, networking (how it works, not necessarily implementing it), software architecture, etc. but focus on what is interesting and useful to you)
