According to https://specifications.freedesktop.org/desktop-entry-spec/latest/ar01s05.html, the OnlyShowIn key is matched against the value of the XDG_CURRENT_DESKTOP environment variable.

For anyone reading this and having a similar problem, I just managed to fix this, by simply purging the unity-control-center. This will change the default one to the gnome-control-center.

Of course I figure it out less than 24hrs after posting. I found that lsusb was hanging. I had a DELL S2340T monitor plugged into one of the USB3 ports (the monitor is a hub and also supports touch via USB...DisplayLink, etc.). Unplugging that fixed lsusb, allowed unity-control-center to display, and also fixed a hang-at-logout problem. No idea whether ...
