I have always run an instance of vnc-server for each user.  I never gave 
the user control, just assigned the port number for the user. I have 
been doing this at least since CentOS4.

Now the fun comes in as to what GUI you are using.  The install is for 
Gnome, and if you want any other GUI, you have work in front of you.  I 
have it working for Xfce.

I have a separate systemd service file for each user. And I enable them 
all, just the way I run things.  I suppose there are ways you can have 
the user start his specific systemd service from their ssh shell.
