Well I do like COMSIC's UI. And Fedora is faster at providing updates and patches.
Maybe you would like to confine your admin account to SELinux's staff_u ? And your user account to user_u ?
It consists of 2 steps, semanage and restorecon.
Semanage changes the account to SELinux's confined user.
semanage login -a -s staff_u <adminAccount>
And Restorecon relables the user's home directory
restorecon -RFv /home/<adminAccount>
Ask your AI for more details.

Yeah, I haven't gotten too deep into Linux hardening yet. I was just reading your thread on your Fedora setup & your Ubuntu hardening. I'll try to look more into it!
