Not who you asked, jumping in until they reply: Windows and most GNU/Linux distros are much further apart than most GNU/Linux distros are to each other. Unless you’re doing a lot of manual meddling or using hacky tools, the biggest change between Mint (Ubuntu/Debian-based) and a Fedora-based distro, in my experience, was that apt is replaced by dnf, so if you install apps from the command line instead of a prettier software manager (I did lots of programming so this was normal for me) then the names of programs and libraries were a bit different. I’d also make a list of things you’ve installed (VPN software, chat apps, etc.) and look them up in the Fedora packages site or their own website and make sure they’re all available. I would assume they would be, Fedora is popular enough.

The desktop environment (Cinnamon vs. KDE) will be an initial change, but they’re both familiar enough with a program menu, task bar, like how Mint lets you carry over some of that same basic surface-level intuition that Windows taught.
