This is precisely the scenario that "trusts" are for.  You can tell one domain to "trust" another. And managing resources becomes basically the same process, and accounts are still a single source of authority (no oddball syncing, etc.)
if all domains are part of single forest then it's easy ...

other option if multiple forest...for SSo multiple forest can achieve using Azure replicating all forests to single azure ad
see the following article

all the best
Would recommend to create Trust between Domain and then user can use both the Domains resource
