What MacBook to buy?

Hi there, I hope one or many of you all can help me decide what Mac I should purchase, and what amount of storage I should need.

I am a second-year college student, and I'm trying to decide between getting the MacBook Air or the MacBook Pro, and I have reasons to get or not get one of them. For the Air, I hear the battery life is amazing, having USB ports is extremely helpful, and the price is obviously nice for a student like me. I plan on upgrading the processor to the i7 for the extra $150 if I get it. For the Pro, I like the screen resolution, power, and overall look of it. What I hate is the USB-C ports being not very student-friendly for flash drives and the cost is much much higher, especially if I am looking to upgrade from the i5 to i7 like I would the Air. I will not be editing any videos, making music, or anything outside of watching Netflix, Youtube, and for class purposes.

As for the storage argument, I use apps like Spotify and Google Drive to get through my days, and I use flash drives often too. I have a very small amount of pictures on my phone and little to none on my current laptop. Because I don't have any need to store documents or music on my laptop, would I be able to get by with the 128GB SSD? Or is the upgrade to 256GB worth the money? All reviews I have read point to the 128GB, but will it be enough to last me a few years?

I truly want a laptop that will last me until the rest of college, so any outlook on this would be amazing. Thank you!
