I'm not saying that choice is plentiful, but it exists. I'm sure there are other people willing to have kids but also wants to progress in their career.

sure, we call those nannies or simply babysitters, depending on the amount of involvement. Not impossible but it is a large expense to consider. Alternatively, be fortunate enough to have trustworthy neighbors who has a stay at home parent who can keep an eye on things for a few hours.
I wouldn't mind a return of the latchkey kid. those stranger danger initiatives probably did more damage than good with regards to letting a kid properly engage with the world.
Also, to maximize health benefits for the children, breastfeeding is preferable (according to WHO, for 2 years), which partially takes away that choice (it's really hard to make a choice against child health if it's purely based on my interest).
I don't know for a fact, but I suspect it is possible to have two parents working from home and an external person coming home a couple of hours during the day and have both career + children, but I'm not entirely sure (my wife is fully dedicated to children, although we are at the tail end).
That being said, the choice shouldn't be determined by sex. Breastfeeding is a thing, but with Canada's paternity/maternity leaves, the problem is heavily mitigated (1 year, although with very low compensation)
