I use M.S. Office Lens at work every week. You can free-crop photos, compose into PDF, reorder pages, etc and save to OneDrive which quickly gets a phone PDF onto my desktop. Brilliant!
OfficeLens also had an app you could load on desktops. I’m sure it was for tablets, but the ability to take a photo, free-form crop and save to PDF was fantastic. Alas, my old install of the app still works, but won’t convert to PDF anymore.
During the WFH situation, I've used it extensively to scan kids homework almost on an everyday basis, to send it to teachers.
I've used it for documents too. And it works just fine.
