That´s up to you, but if you´re going to do a clean install, there may
be no point in converting to BTRFS first. Just back up everything and
install F34 with the defaults when it arrives. Shouldn´t be too long
now. That will get you BTRFS out of the box, though the installer might
ask you, I forget.

The Fedora 34 default is BTRFS indeed, no questions asked :D
