nope, since fedora 38 this button enables full access to flathub. it also lets you install proprietary nvidia drivers from gnome-software with one click. hardware decoding via ffmpeg also works for flathub apps that require it.
yeah, the firefox situation is indeed still confusing. you make a good point. deleting the stock one and installing the flathub one + ffmpeg-full(flatpak) seems the most straight forward solution for hardware decoding. but as you said still fairly confusing.
I do still think ublue is more confusing to understand, personally
