There were some really interesting analyses presented by a dating app several years ago (I don't remember which; they had a blog and I'm worried it's now buried outside of Google's apparent time window). One of the most interesting things was that there was a mismatch between men and women in interest versus openness and confidence. I don't remember the details, but I think the problem was something like women were more interested in a wider range than you'd think, because they were more afraid to approach/make contact with men they were attracted to, and men were more picky about attractiveness but also more assertive about contacting women. The net result of it all was that there were these attractiveness ranges that were being neglected not because of attractiveness per se but because of complicated dynamics in confidence of approaching at different levels and how different genders on average acted on perceived attractiveness.

The analyses were like gender x attractiveness x willingness to approach x receptiveness to being approached. It looked like all four variables interacted at some level.

Maybe it wouldn't generalize and maybe I'm remembering it incorrectly but it was something like that.
