Going to try and think outside the box here.
When making your decision, potentially take into account that most information today can be self-taught via online courses/books/resources. So to my point, you could try and choose something that you would find to be potentially difficult to teach yourself alone and where you could really benefit from having a professor walk you through the process via homework, test, papers, office hours, etc.
For example, I was an Economics major, business/communications minor but I have an interest in Computer Science. Computer Science, to me, seems a lot harder to follow via the online resources. So I personally would have preferred to have had a professor walking me through the process in a physical classroom rather than attempting to teach myself online.
Long story short, consider choosing something you may dread teaching yourself later in life where you could benefit having a professor walk you through (e.g. Finance/Accounting/Comp Science).
