I'm a man and I definitely prefer long hair. Its not not that short hair can't look good, its just that longer hair always seems more feminine.
I don't think its any objective beauty, more that having long hair is a lot of work, so it is only indulged by those who care most about their appearance. The same of course goes for almost all beauty treatments of either sex, such as tans, muscles, cuts, dyes etc. There's a psychological term for this but I cant remember it, something to do with a show that can only achieved with significant personal sacrifice, making it scarce, and therefore valuable. Can be a Ferrari, an obsessional beauty regime or anything else.
As a perhaps more direct response to your question OP, I was watching songs of praise this morning. 99% of the women had short, grey hair. Good for them, but the default for women who are less interested in their looks will never be particularly attractive in my opinion.
Put a skin fade and some tram lines in and you're alternative, that's a different beast, but low maintenance will never be particularly attractive in either sex.
