Is there any video series that cover best practices for sever configuration and imaging?
Windows Server 2016 and Imaging
I hope all is well. So imaging is a many splendid thing these days, as you can use a multitude of platforms to accomplish this. It would depend on what tool set(s) you wanted to use or learn more about.
One option may be my
Hands-On with SCCMshow (System Center Configuration Manager), in the
MICROSOFTsection of the library does go over how to do image deployments using the Operating System Deployment (OSD) capability of the SCCM platform, which is really the Windows Deployment Service (WDS) under the hood.
I go over how to image using a Windows 10 O/S, but you could follow the same steps, just swapping out the O/S, and easily do the same thing with Server 2016/2019.
Hope that at least gets you started.
Good luck !!!
