Someday you may well get a work-issues Windows laptop, so know how to use one, whatever you pick. I prefer Macs for personal use; at work, you don't always get a choice.
I wouldn't get a really old Mac as there's a limit to how long they'll issue security updates, and I wouldn't get an Intel Mac now since some software requires M-series chips, and they tend to get good battery life, which may matter when you want to study at the library, if you take it to class, etc...
This thing will be general use for education and entertainment; I wouldn't try to make do with an iPad. You'll likely be using the school's online system to submit work assignments, etc... Yes, you can use a keyboard and mouse with an iPad, but seriously...
I'd get a MacBook Pro because people praise the superior screen and you may be looking at that screen a LOT.
I wouldn't get 8 gig RAM; I'm told it can lead to the Mac using the SSD more to compensate and SSDs eventually wear out with use. There's also concern A.I. features going forward will benefit from more memory (and neural cores in M-series chips). Even the iPhones are reportedly going up in memory with this in mind. For a Mac, 16-gig might be fine; I'd go no lower. Due to the number of chips in SSDs, I'm told the 256-gig were slower than the larger ones, and few people wish their main system drive were smaller. At least 512-gig SSD.
A broad liberal arts university education is enriching and for many of us well worthwhile, you learn things you'd never have studied independently, few people have the vision, discipline and ability to wrest a university-class education out of a library card, and the degree is an important credential needed for some jobs and post-graduate professional schools. If someone people have server-class blue collar jobs with degrees, I'm not sure a high school diploma, library card and your word you read a lot is going to cut it in a competitive market.
P.S.: August was last month, so I assume you made a choice. What did you get?
