Does a minor effect career prospects or valuable skills?

Hi all,

I am a senior applying to schools right now, applying for Finance concentration/major at business schools. I am wondering: for career purposes, are there any relevant minors of study that could teach me skills or make me more qualified to go into different industries? In other words, does the minor even matter? I know this is an immensely broad question, but I am trying to navigate what to study to broaden my skillset. Examples: Comp sci, data science, economics, etc.

Thanks in advance to anyone sharing their experience.
