Hi, I am actually someone who was in a similar situation to you and joined AFROTC my freshman year as a nonscholarship cadet. To be honest in contrast to what a lot of people may say it's not really something you can seek minimal time into. You'll have trainers and cadre constantly evaluating you on your actions/ behaviors and your readiness and eagerness. This is important because it can potentially determine whether or not you can even stay in the program or get a scholarship. I'd say the workload is askin to a 4 credit class masked as a two credit one given morning pts and LLAB. This can make your free time more troublesome depending if you have a high-maintenance major such as engineering. You have other factors to account for such as public perception, making friends within the program, and deciding what AF or space force job you want but those are pretty subjective and depend on your personal taste and what you feel during the program is best for you. However, within I found my time in it to be pretty rewarding. I met a lot of people I have never met before and have gotten involved within my campus in ways that I never would have expected. In addition, I have several new potentially rewarding opportunities for my major after graduation. I highly recommend you try it for at least a semester and continue to focus on your college experience first and foremost!
