Just be aware that Fedora's got a six-month release cycle rather than whatever Ubuntu's LTS lifetime is (4 years?), and Fedora only supports current release and one back. So realistically, you've got a year a month to upgrade your workstation.
I've had Fedora for over five years and I've never had my laptop get completely borked by an upgrade, but I've had just enough things break between releases in the past that I still get get the sweats every time I've gotta do the restart upgrade, whether it will come up completely and just work or whether my WiFi is now broken because resolve-d changed to systemd-resolved.
Actually regarding upgrades Fedora Silverblue - which I currently use - may be better.
Key benefits:
- Applications through flatpak don't depend explicitly on system libs so there's less chance of breakage.
- If upgrading to new fedora version breaks anything, switching back is just one command away (rpm-ostree rollback). I don't think going back is so easy on normal fedora.
