Both are great options, but if you're happy with Fedora, there's probably not a big reason to switch. Arch is a full rolling release, which requires you to be aware and ready to deal with any breaking changes each time you update your packages. On Fedora, you'll mostly only have to be ready for this on a new version release. If you want to always have the newest packages for everything and don't want to wait, then CachyOS is great. If you want to turn on auto updates and only think about changes when a major release drops, Fedora is a better pick.

Bazzite, being an atomic distro, is kind of hard to compare to. For basic use-cases like running just software available in Flathub, it is incredibly solid and easy to use. If I were choosing a Linux distro for a non-technical family member, I would go with an atomic Fedora distro and be completely confident they could get things done without breaking anything. However, if your needs are more advanced, you're going to need to be ready to relearn a lot (e.g. using containers for development), since atomic distros are a big paradigm shift from standard ones. This isn't a bad thing, just something to be ready for.
