2.4 is not the end of the world, but obv 5.0 is better
Fwwi, that's a misunderstanding. 5GHz /can/ be better and typically is on close, unobstructed distances, but 2.4GHz has a longer range and more capacity to penetrate walls etc.
Also the signal vastly depends on the noise, ie. if everyone's using 5GHz and you're the only one on 2.4GHz, you'll typically have better a signal and possibly throughput.
How's the signal in the cafeteria and the library?

Sorry, I haven't been to the library until now.
Anyway I ran
iw dev wlan0 scan | less
while having the card that could only do 2.4Ghz and it returned this:

The signal, if I understand correctly, is much stronger on 2.4Ghz, but still it wasn't connecting in my classroom

The above output is from the classroom?
The channel is more crowded but the signal much stronger - do you have a journal for that supposed connection failure?

The above output is from the library
I'll try to get the journal for that tmr

Sorry for the late reply, but I have been through some tests. After the test I won't be back at school until like February so... yeah. The places that I take this thing to have been alright regarding wifi, so probably when I got back I'll open up a new threat if the problem still persists.
Thank you so much

For anyone else who stumbled on this question, I ended up reinstalled Arch entirely, new physical drive and everything, during my trip in the holidays, I got back to school a month after and it kinda works? Definitely something wrong with my configs and/or services/packages. It should be noted that I used
archinstall
in the first install and I installed manually (following the wiki) the second time. Perhaps there was a bug in the script?
Anyway that should be beyond the scope of this question, marking it as sovled
