There's also https://sendfiles.dev/ https://sendfiles.dev/ for browser to browser transfers. You could also self-host an FTP server (or something more modern like NextCloud) and open a port on your router to let users download (and take it a step further with a dynamic DNS provider in case your IP changes). I agree that it shouldn't be this hard just to transfer a file.
