I'm not sure you're right, I can't find information regarding whether users are confined by default on Fedora (Red Hat docs seem to indicate the users are unconfined by default).

Edit: They are not, see https://docs.fedoraproject.org/en-US/quick-docs/selinux-getting-started/#_selinux_examples, specifically:

SELinux can confine Linux users. A number of confined SELinux users exist in SELinux policy. Linux users can be mapped to confined SELinux users to take advantage of the security rules and mechanisms applied to them. For example, mapping a Linux user to the SELinux user_u user, results in a Linux user that is not able to run (unless configured otherwise) set user ID (setuid) applications, such as sudo and su, as well as preventing them from executing files and applications in their home directory. If configured, this prevents users from executing malicious files from their home directories.

ls -Z in any user home will show they are unconfined_u (so will id -Z).
