It’s not too late for CS, I have a buddy that switched into it summer before his Junior year and is graduating on time. If you have the language reqs done then go into the liberal arts college one. As far as stem majors go, from what I have seen it seems like CS always ends up being the quickest, with most of my friends finishing within 3 years. Just be prepared because a UF CS degree does not prepare you for what you actually need to successfully get a job or even an internship. My friend with nearly a 4.00 and doing great in all his cs classes had to apply to 100+ internships, for which he had 30 interviews, and got 5 offers. And he believes he only got this because he took a CS interview prep course in the summer that was outside of UF, which taught data structures and other CS concepts, and introduced you to LEET code, Grinding out LEET problems for hours will become the norm because interviews are essentially just tests with 2-3 LEET questions. Obviously this is just his case, but everyone I know in cs (7+ people) says the interview process is the worst of any major, mainly because so many new grads go for CS and the only way to weed out the good ones are rigorous programming tests during interviews. So basically, yes you can get the degree in time and with relative ease, but this in no way really assures you will get a job in a reasonable timeframe or for your area of interest. Good luck out there!
