But if one day I have a newer graphical card, what will I have to do?

Yes, update the kernel and run

sudo ubuntu-drivers install

@nonobio

Also, do you share the Storm's opinion about source choice, and do you recommend too to choose Zorin source instead of Flakpak for an old PC?

Yes. Absolutely.
