"but how many people have Ethernet at their doorbell?"
With PoE and a UPS too.
Your front door by definition is on an outer edge of your house. You can run conduit externally or whatever internally. It isn't beyond the wit of man to deploy wiring. If you need your "smart" doorbell to always work then you will get ethernet to it and ideally PoE too to power it. A UPS will keep it alive when the power is out.
I also recommend that it is able to trigger a non smart chime too so if all "smart" stuff is unavailable, you still get notified.
When my home (Doorbird) doorbell is pressed: Separate battery backed chime goes off, Sonos speakers say "Ding dong, there is somebody at the door", TVs get a notification, our mobile phone apps twitter.
It is still possible to miss a doorbell press but quite hard. I do all my IoT stuff like that if possible - important stuff still works without the hub/internet/Home Assistant.
