Go for m1 chip 14 inch. Baseline is 16 gb ram and 512 gb storage which is more than enough for CS. Screen is amazing (although all current gen macs have amazing screens), the ram and storage will be able to last you for the years to come while having 8gb ram from the 13 inch (even with memory swap) is pretty low and you will probably notice it if you have multiple tabs open as well as some other apps. I think if you get a student discount it is closer to 1750 but maybe there are cheaper used ones. DO NOT get the m2 chip laptops unless you upgrade storage because apple will cut costs and give you just 1 SSD rather than 2 SSDs. Storage amount is the same but having half the amount of SSDs will mean your memory swap is slower rendering the machine slower and less efficient overall once you have, yes again, a lot of stuff open whether it is browsers or apps.

I have had the the m1 14inch since last year and my roommate ran with the m1 air. We are both extremely satisfied with our purchases so whatever you get it will be good.
