For the "I'm scared of computers" crowd, isn't it still a bit hands-on to get proprietary codecs so you won't run into to problems watching things like YouTube?
youtube specifically, no, because youtube will do vp9 fine. Other sites though, which use h264 will be a bit problematic. Still, you can install chrome for that crowd, and they'll be fine too. Alternatively, you can enable rpmfusion or other third party repos, which has become a bit easier (almost too easy unfortunately) in recent fedora releases. I'm personally not a big fan of this direction though because it blurs the lines between official good quality software, semi-official software that is mostly fine except for patent trolls, proprietary drivers, and random proprietary software delivered through flatpak/snap etc. Currently, all of these are almost enabled by default, or are just one click away.
