IT vs Computer Science vs Accounting

I'm looking at going to WGU debating between these two fields. IT seems like the fastest route, but a lot of the jobs are help desk that are contract and pay low, or not much more than I'm making now (currently make around 38k so I'm looking to major in something that will give me a good return). Computer Science, I'm worried about the salary and most of the jobs are in bigger cities. Accounting, I don't want to get the CPA I just want to do industry, but is it possible to get a job without CPA, and how do the salaries compare to computer science and IT? Also, what career would be best suited for an introvert?

So which of these careers is best in regards to salary and opportunity wise?
