I haven’t watched Wakanda Forever, but […] Looking at some of the complaints, it appears to have a similar problem to other modern Disney films, in which women are put on an elevated pedestal and men are left to be bumbling idiots completely incapable of basic human functions.

No, not at all. There are three male characters in the film (Winston Duke’s M’Baku, Martin Freeman’s Everett Ross, and Tenoch Huerta’s Namor), and they are all very competent. One is a CIA agent, and the other two are leaders of their people.

I did watch Black Panther […] I do recall noticing that Disney chose only white actors to play all the villain roles in Black Panther

The villain in Black Panther was Erik Killmonger, played by the very black Michael B. Jordan.
