Migrating from AD hybrid to new AD because of company adquisition.
I have this scenario where a company have an on-premises domain syncing to Azure AD, and using standard on-premises services like file servers, and also Microsoft 365, all type of Azure services, Int...
Technically it is more like a rebranding, but not sure if that can be done. The old domain company.com, needs to disappear and become parent.com. But everywhere. On premise, on Azure. It will affects everything.
No sure what is the best patch considering the sheer amount of moving parts. In an old world migrating to a new on-premise domain should do it. But because of the deep integration with Azure and Office 365 tenant, the problem is way more complex.

Ok, cool. Unless I've misunderstood, I would recommend trying to go down the route of adding partent.com as an additional suffix to the existing AD, and then adding parent.com to your AzureAD Connect/AzureAD.
While the AD domain internally would still be company.local or company.com, adding parent.com as an additional suffix means that you can change users UPN from email address removed for privacy reasons to email address removed for privacy reasons. so for sign into the domain and Azure they would use the new suffix (as well as for email etc).
While there would be some reconiguration, it would certainly be less disription than ripping out AD/Azure and starting over again.
If there is a real need to rename the On Prem AD domain, there is a process to do this, although I've done done this myself and is quite involved.
