The Fedora installer has let you choose between ext4 (and ext3 before it), XFS, and BtrFS for like, more than a decade? This should not really influence your distro choice one way or another.
It's defaulting to btrfs, which is a poor decision. If Fedora is making such poor decisions on basic things like default filesystems, that gives me more than enough influence to chose one way or another.
They were all aboard with Stratis, but here we are, btrfs moving back in.
