Question on internships/jobs/experience acquirement

Right now I’m a freshman in my first semester, and I wanted to do some extracurriculars. However, if I were to do something extracurricular I would want it to be career-oriented. The problem is, I’m not sure what I want to do for a career. I mean, I have it narrowed down to a couple fields but they’re kind of disparate. So what should I do? In addition, how do I know if a certain internship/job I’m looking at is quote unquote top notch or will look well on future job apps or will provide me with good experience?

An internship might be of help don’t you think?
