Microsoft charges next to nothing, and even subsidizes hardware, for edu MDM'd devices. Basic services are more expensive than enterprise, but not by much.

The second you want any educational specific SKUs, though, holy shit.

I think Microsoft, Github and many other companies also provide many free/subsidized services to those who can prove they're students, that includes even web hosting on AWS or digital ocean IIRC. Even leaving those aside, there are also plenty of open source options (such as LibreOffice) for those "services" and software that kids find useful.
