Federated Authentication in ABM?

So, I should have asked this sooner but any thoughts on whether or not to use Federated Auth in Apple Business Manager? We’re a 98% PC shop with some one-off Macs and just now starting to support Mac officially. So I set up JAMF Now Plus (the “lite” version) and ABM. I chose to use Federated Auth thinking it would be good to link our O365 credentials with the Mac Apple IDs. But I have name conflicts and a mess on my hands that may take 60 days to resolve and new machines waiting to be distributed now. Thinking I made a mistake.
