Not sure if it counts, but gnome-font-viewer might fit the bill.
You can probably run something like gnome-font-viewer /usr/share/fonts/open-sans/OpenSans-Regular.ttf and it should show you the font, although I haven't verified that myself.
Here are it's dependencies:
$ dnf repoquery --requires gnome-font-viewer

It does also let you view fonts installed on your system, but I don't see why that should be a deal-breaker.
There is also the display command, provided by ImageMagick. My understanding is that it only supports X11, but it should work just fine under XWayland.
