I can’t help with your question as my Eras are music-only wall-mounted units, but I’m curious what ceiling mounts you plan to use? Presumably you’ll then mount them in the inverted orientation?
These ones, and I would do inverted orientation: https://a.co/d/2wHboOZ
No idea but I wonder how they would compare to an Amp and either the 6 or 8 inch in-ceiling speakers.

Amp powered passive speakers won’t support separated Atmos rear channels, but I really doubt that ceiling mounted Era300 would so that quite well. I definitely would prefer floor stands, but as OP said it’s no option for him.
Imo both options, ceiling mounted Era300 and passive in ceiling speakers are difficult to test.
So I think I would go with a pair in ceiling speakers.
I used Atmos for some time with non dedicated Atmos rear speakers, and nevertheless it sounded much better than DD5.1.
