Just wanna share what I think about matriarchy. I've read many stores with matriarchy worldbuilding and here is what I think the types of the status quo shifts between male and female in these stories.

> Always has been
that female always has been the dominant sex of human society
ex. Stories you guys had been sharing on this thread, also I forgot to note most story I read where women always has been dominant and have unique society compared to our own.

> Evolution
females gradually becames the dominant sex in span of centuries
ex. Blessing of the Goddess by Vicoc055 (https://archiveofourown.org/works/21446050/chapters/51104797)

> Rapid Change
females rapidly becames the dominant sex within a generation
ex. Gyarussic World by Akane (http://omnitopia.bplaced.net/)
ex. The Infomercial and Brawnafied World by MagnusMagneto

> Instant Change
there was a trigger that changes the capability of females in many aspects that it was enough to overpower males
ex. Alpha Gender by Mikethat3DGuy (https://www.deviantart.com/mikethat3dguy/gallery/74302062/the-alpha-gender-story)

> Real World Mirror
Just our world we currently live on but flipped
ex. manga The World of Moral Reversal, manhua I Eat Soft Rice in Another World
