FWIW - we're not an Azure shop so aren't using Windows Update for Business or Microsoft Store for Business If you haven't seen it already, I recommend reading this post in the Microsoft Tech Community: Endpoint Protection Updates for Configuration Manager.
It gives a good explanation of what the update source options actually do.
For earlier OSes you'll need to use this script.
I only ask because I'm wondering if it might be the best option for our environment.A large number of our Windows 10 endpoints are laptops and those users are often out of the office in remote areas so will have an internet connection (at best).If they really want to connect to the corporate environment it would be via VPN.Like mentioned, use Microsoft update if you can for the smaller payload.I use fileshare / mmpc on desktops, and mmpc on mobile devices.
