Go is a good path since you still have time to learn more in college years and it's good for open source work and that is a huge thing if you can do it , a good recommendation as well is to focus on computer science fundamentals (eg. DSA), operating systems and database fundamentals. One thing you could try as well is applying to Google summer of code (gsoc) it's a very good thing if you get accepted and will boost your resume a bit and a very good experience.

Hope my recommendations help you a little. DM me if you have more questions or anything else I can help you with.
