2 packagers but 3 packages?

Flatpaks are better on the assumption that the sandboxing does not block anything you want it to do - but that's a big assumption. For example, I tried running on Silverblue, but found that the way the GNU Emacs Flatpaks behave (both Fedora and Flathub) was incompatible with my workflows because of the sandbox (albeit I've since switched away from Emacs)

But (as a counter), I'm happy with LibreOffice from Flatpaks, because the sandbox doesn't get in my way. I'm slowly removing non-Flatpak packages and replacing with Flatpaks, with the intent to switch over to Kinoite (because I keep coming back to preferring KDE to GNOME) once I've reduced my system to one where all applications I use are Flatpaks.

That said, your software setup should only show you one of the 3 options at a time; I've just checked KDE's Discover, and there's a button at the top-right to choose a source - either "Fedora Linux", "Fedora Flatpaks" or "Flathub", with a different icon for "Fedora Linux". It also has a default choice it makes, which can be set by the distro; I believe that 99% of the issue is that Fedora's default was set to prefer Fedora Flatpaks over Flathub, and Flathub over RPMs, and if it were configured to prefer RPMs or Flathub, the issue would be less serious.
