I think the scheduling is still stuck in the mindset of a time when very few games were available on broadcast or streaming. Now almost every single game is available on some platform or another. It makes no sense to have all the teams in a power conference in action during only two time slots on one day. This is exactly why the men's games are spread around much better.
There is truth to what you say, particularly regarding the men. Because many men's games are televised, they are often spread out to accommodate the various broadcast contracts.
In general, at least based on what Vivian said and things I have read, conferences tend to schedule games on regular days because it not only helps with regard to the (limited) television contracts, but also helps with the scheduling at the schools regarding classes and such. Hence you have the PAC and their travel partners, the Big East also does travel partners. But playing set days helps with setting up the teams practice schedules and players classes. It is also easier for the conference, especially as they are scheduling men and women both who very well might share a facility.
Incidentally, and you probably know this, that's why women's schedules come out after the men.
