So if we want provide multimedia keys that works out-of-the-box on all
platforms, without adding keybinder dependency, what options do we have
really? I suppose the mentioned amixer is not available on
OpenBSD or any non-Linux.

Maybe have a configure option to libxfce4ui?

 ./configure --volume-up-command="mixerctl outputs.master=+10"

The configure script could autodetect it to something sane:
