However if I understand it correctly this does only work with English right now so should we consider to add the users language into this?

The country names should be translated, that is handled by:

Intl.DisplayNames(language, {
  type: "region",
  fallback: "code",
})

Right. Didn't actually check, just looked at the language constant.
So this should be good to go.
