Why can't I open system-config-* gui for anything?

I'm the root user of my own desktop Linux (Fedora 29, GNOME 3.x). I used the command su -, followed by the password to access root accesses. I'm attempting to access the graphical tools that are supposed to come with Fedora and RHEL systems via the command line. I have entered system-config-* for the following instances of *: bind, httpd, nfs, rootpassword, samba, service, gtx, date, firewall, language, printer, and users. I also attempted to access the SELinux management using policycoreutils-gui.

In every case, I get a command not found error. For 3 or 4 of the commands, there is an attempt by the system to download the services associated with that command, but the GUI fails. The closest I get to success in accessing these system-config tools is for system-config-language. It says the GUI has failed to load, but at least provides a text-based solution. At the command line, I am only typing system-config-* or policycoreutils-gui and nothing else. How can I access these GUI utilities?

It is a policy decision by the Gnome project to disallow gui programs to run as root. See for example this answer.

Some of the system-config have a replacement in the Gnome settings, for example time-zone configuration or user and group maintenance. For others, the cockpit package could be a valid replacement.

Some of the system-config programs depend on python2.7, and as python2.7 is about to be retired, the system-config programs either needs to be converted to python3 or they will disappear. system-config-date, for example, is already dead.

I'm too new to uptick your answer @villykruse, but this is an informative and thorough answer. Thank you!
