Entra Registered vs Entra Joined

Hello All,
In a workgroup environment, all devices are Entra Registered, and Intune enrollment is enabled for the group. I understand that Entra Joined devices have greater management capabilities in Intune than Entra Registered devices.
Could you clarify which features or policies are not available for Entra Registered devices compared to Entra Joined by Intune? Please share any relevant Microsoft references.
Thanks
