It can take some research and tests to understand the difference between different Azure AD join types.
I summarised some key differences in the following.

As more and more staff work from home, IT starts to consider solutions to allow remote identity management without relying on line-of-sight to domain controllers. so:
- If you want to login to a computer by authenticating to Azure AD, you will need to unbind the computer from on-prem AD then bind to Azure AD. A hybrid Azure AD joined computer will still authenticate to your domain controller
- Microsoft recommends to use the MDM-only approach to manage all Azure AD joined devices, instead of co-management with SCCM.
