I think this has gone well beyond being "choosy" and has spilled into the realm of "just not even trying". See this article: https://www.pewresearch.org/social-trends/2020/08/20/a-profile-of-single-americans/ Of the 31% who are single, half of those aren't looking for any type of relationship at all. For women, 62% are just choosing to not even look. So, that is the real choice due to all the factors mentioned in this article that women don't "need" a man anymore, so choose not to have one, period. So it's not like they've "raised their standards", just a majority of women won't pick any man at all. This does not bode well for the human race.
