From a British perspective, I think you’re over-loading QE’s failure to be as open with Jackie during the scone tea. To me, it felt more like a comment on British upper-class reserve rather than some symbol of the patriarchy.

If you’re interested in a fun, sort-of biography of Princess Margaret, I can very much recommend “Ma’am Darling - 99 Glimpses of Princess Margaret” by Craig Brown.

As a couple of recommendations - Netflix has an excellent series on Auschwitz from the BBC. Also, if you’ve not read it, Primo Levi’s “Is This a Man/The Truce” is one of the most evocative and oddly uplifting accounts I’ve ever read - both of the life of the camp itself, and an extraordinary journey home afterwards.
