Probably not all that unconventional but we're opening up a Canvas 'course' for our HR group to be publicly visible. Their modules will cover all the onboarding necessary for new employees without any need for login credentials. (not sure why a web page wouldn't work but here we are. ) This will be up, shortly.
We have peer mentor services where we enroll FTIC and transfer students (separate courses) where these different cohort of students can login to get resources and arrange for tutoring, advising, and basic needs help, etc.
We have continued ed classes and a police academy using Canvas but because their semester cycles are vastly different we are using a different enrollment tool that also takes care of billing and is completely run by their respective departments.
In a previous LMS faculty were using courses as a method for Rank and Tenure processing. They had templates of different folders that candidates uploaded their previous scholarly work. That said, we moved that over to TEAMS but the word on the street is they are going to move this to a proper enterprise software application, shortly.
Hope this is helpful.
