I have a similar usage pattern where there might be days at a time where I don't boot up my personal laptop. With an 11th Gen and Fedora I set it up with a swap partition and force it to hibernate after 30 minutes. So far it's worked well.

It can take 10-20 seconds to boot up but battery drain while not is use has dropped to maybe 2% for any extended periods of non-use. As an 11th gen user, it exacerbates the CMOS problem I mentioned earlier but that hopefully shouldn't be an issue with the 12th gen mainboards.

This is a guide I've seen recommended: https://community.frame.work/t/guide-fedora-36-hibernation-w...

Hope that helps.
