My GF Macbook Pro has reached end of life support - sh.itjust.works

Hi everyone, My girlfriend has MacBook Pro from 2012 which has already been upgraded with more Ram and an SSD. From what I understand, her OS (Catalina) has reached end of life in 2022 and doesn’t get any support from Apple anymore. As that machine works perfectly, what should she do? I hate Apple products (even if it’s painful for me to say that they’re good) and I’m a Linux enthusiast, so I’d tell her to install Fedora Asahi, but I wanted to know if the Apple enthusiast crowd had a better idea. My girlfriend isn’t geeky at all (despite her geeky glasses) and she would want to stay in the safe environment provided by an Apple OS. But we also don’t want to replace that powerful machine as we hate programmed obsoletism.
