I think than some two of the prerequisites are the real problem :
* Great cameras
* Stock Android OS
There are plenty of recent small smartphones with a display under 6". But most of them use Android Go and a not-great camera. I have recently tested one, the Logicom Le Wave, a 60€ phone with a 4" display sold in Europe.
During my test, i have find Android Go 11 very reliable. It's even more easy to avoid using Google applications and to not link the phone to a Google account (by using F-Droid & Aurora Store) than Stock Android. There are also nice features for managing battery usage. That said the two cameras are indeed crap (but i do not take photos with a phone, for this i use a real cameras). My main problem with this phone is that it's also bad for... phoning: I mean than the sound quality is crap too.
I was probably unlucky with my choice, but there are plenty of alternatives for 4" to 6" smartphones. Search for "teenage" or "unbreakable" phones.
If the real objective is to have a light phone, who fit nicely in the pocket, than can be used one-handed and who won't fall out of the pocket while bicycling, then this sort of phones are perfectly fine. So my question is why the need of a good camera and stock Android ?
(For the main point, i agree with you, smartphones are becoming ridiculously too big)
