I also have Fedora 35 and umask for root is 0022. Anyway, it is not
necessary to install TL from TUG as a root. If it is installed by an
ordinary user in /usr/local/texlive and PATH added to bash profile for
all users (must be done by root), then that one user has r/w access
and can maintain it and other users can read and execute.

It may also be different whether you do su - and then call tlmgr or
whether you use sudo. Anyway, umask is the first thing what you should
try.
