Since they were very small, I’ve always just approached gender tropes with mild puzzlement, and asked them a question. I’m still finding it a useful strategy.

Often a question doesn’t need an answer, as much as it needs a chance to express their own confusion or discomfort and have their feeling sense checked by a trusted adult. If you rush in, even with a wise answer, that opportunity can be missed.
My dc are now in a stage of life where their default position is that parents don’t understand very much of anything. They don’t put much store in my opinions or wisdom, so I don’t waste my breath sharing them, except as context for my struggle to grasp the finer points of the modern world.
