What kind of programmer?

Hello from Sweden! I've recently taken an interest in IT and programming. I've gone through the CS50 course just recently and I loved it!

My question might be dumb or i might be confused but i was wondering what kind of programmer has the broadest range of opportunities in the future. I've seen something called front/back-end and fullstack, are there any more "types" and what could possibly give me the best future that could get me into "most" Jobs?
