On the other hand you expect that newbie developers should prepare their own minimalistic stack which I dont believe is true.
New developers should start playing with plain JS to learn language itself and pick some opinionated stack/framework to develop production stuff. Boilerplate with good architecture and pattern examples is all you need.
Regarding React+redux ecosystem I think it have very good separation of concerns developed with presentational components and containers so new developers can fast jump in and be productive.
Yes we are missing some open source series about high level architectural patterns, not only JS patterns. There is a lot of information, but some quite outdated and not connected so no short time high gain. But scattered around the web.
