In terms of business matters and for managerial work, I actually prefer to choose on the individual's skills, not on gender. But I understand that in some places or countries, gender conditions can affect individual performance.
In my country I prefer men for work. Why not to choose a woman? If you choose a woman, there will be a decrease in performance when her emotional unstable, pregnant, high stress levels, sometimes the decisions made by women are influenced by those closest to them/their family.
It's true, gender shouldn't be a separator because in a business what is prioritized in my opinion should be skill, responsibility, professionalism and so on. If someone is a woman but they have the criteria to be able to manage a business, will we miss them? I think it would be a shame if we just missed it just because we look at gender.
However, in some communities or even countries, men are given priority. Maybe they have reasons for doing that, one of which is as you said. Apart from that, it is possible that men's time effectiveness is more flexible than that of women.
However, if I could decide, I would not look at gender differences, but would look more at the skills and responsibilities they have.
It is already known that women of today can be as good as men, gone are the days where women only serve as assistants to men. In fact, there are a lot of successful business companies that are led by women, which proves that women may also outsmart men when it comes to skills and performance.
