But surely, an adult who makes a conscious decision to enter the CS/IT field knows about the different domains in a much more real sense. Why would a woman not choose a CS career path in that case? She would know the difference between a technically challenging programmer position vs a support desk job.

The humans I've run into who didn't choose a IT career path definitely know nothing about the difference between programmer, sysadmin, and helpdesk, not even that the differences exist. If I didn't have an uncle in the biz I wouldn't even know there's a categorization of rough/structural carpenters and finish carpenters. I don't think most people make career decisions based on extensive rational data gathering of the whole human experience of work before picking a career.
