New on-prem AD with existing M365 users

We are currently cloud only with M365, AAD joined devices, and using Intune for basic management. We are growing and will need a couple of on prem servers.

To simplify access and management, I'd like to create a new on prem AD domain and sync the existing cloud users. From what I have read, the following is the basic process:

  1. Export all 365 users to csv with all attributes
  2. Import all users to new domain
  3. installing AAD connect on-prem
  4. running initial sync

Is there anything else that needs to be done?

One thing to note, when the M365 tenant was originally setup, there was an AWS hosted DC that had AD Sync running. That was removed 6 months ago and all users are now cloud only. Will I be able to use a differenet domain name than what that server originally had?
