There's no shortage of ways to share files with other people, whether you want to send them in a group chat, attach them to an email, or ping them over via AirDrop or Nearby Share. These all work perfectly well, but they're all best for smaller files.
In addition, if you're looking to limit the amount of time a file is available for download, or if you want to limit who has access and the kind of access they have, a more feature-filled app is probably better.
Below, I look at the file sharing options offered by Apple, Google, and Microsoft, along with a couple of third-party apps. There are loads of the latter out there; I've just listed one of the most popular and one that I've used several times.
