Help creating Device groups

Hi,

I'm new to using Intune on a day to day basis, after adding our devices to Intune via our On-prem Active Directory.

What's the best practice for organizing our Devices, such as Staff devices and Student devices?

I want to create a group for all staff devices and another for student devices.

Also, is there any way to auto enroll these pcs in to the correct groups once they're new ones added via our on Prem AD and Entra?
