I think that is more to do with your interpretation than what women actually say.
Here's the cliff notes for how I see it.
Men and women have different bodies and to a small degree at the population level we see biological differences in character, mainly to do with agression and risk taking. However, at an individual level men and women display a lot of overlap - plenty of women are more agressive and risk taking than plenty of men.
On top of this is a huge amount of socialisation where different behaviours are rewarded or punished depending on ones sex. This is not just, indeed mostly not, simple obvious stuff like parents telling boys not to be babies and girls to play nicely, but the cumulative influence of all the people we interact with, hiw they treat us and how we observe them interacting with each other, the stories we are told and the media we consume, millions and millions of tiny message about what it is to be a woman or a man and how those intersect with all the other social cues and rules we internalise, and also what we as women or men can expect from others, women and men.
And then on top of that, Feminists are trying to unpick it again to understand who we as individual women really are, what we could be outside that framework, while also dealing with the reality that the framework still exists and doesn't just influence how we feel and act but also how others see us and treat us, and a man's belief that we are only there for sex, for example, or an employer's belief that women are not as strong leaders as men can still hurt us whether or not we see ourselves like that.
So yes, there is an element of "sugar and spice, slugs and snails" but it's not describing what women and men innately are so much as current socialised behaviours that need to be managed if women are to have the freedom to take as much advantage as they can of their native talents and live the best lives they can within this society.
One of the Gender Absolutists, I forget which but Howse or Emily or whichever one it is on this thread, currently has a bee in his bonnet about "is" and "ought". He thinks we think that because it is necessary to have sex based protections and supports today, we think that is the way it ought to be.
For me at least, that is a fundamental misunderstanding. I recognise it is necessary today because of the marginalising or exploitative behaviour -physical, sexual, social or professional - of some men towards women today. But I believe those protections ought not to be needed because that behaviour ought not to be happening.
As a Feminist, I am entirely capable of separating what we pragmatically may need to support women today from the more equal and safer future I hope we can build towards for women tomorrow.
