Men could benefit tremendously from true equality because that eliminates toxic masculinity and gives more freedom to men to feel their feelings, admit their needs of being supported and comforted and it also would take some pressure away because by not being thought of as inherently superior and more able, it would be truly ok(not just legally or whatever but with no social stigma and conditioning to affect self esteem and self worth) to not be the one earning more money, being the "strong" one (which just means denying yourself the need for comfort and help).

Yes, men would have to pitch in equally with house chores and the nasty bits of having a child and would not be able to randomly objectify and sexualize women at every step or feel innately superior over this one category, but that isn't right away and that privilege and comfort comes with the oppression and dehumanization of women. Having these privileges is not a privilege at all actually.

There's a lot of freedom is being allowed to be imperfect, because no is perfect, no one is inherently stronger or weaker and feelings or the need to be helped, having bad days, being sad, feeling loss, needing love, crying...those things are good to have freely because we all have them and when men are sort of pushed into repressing them or just not dealing with them, that ends up keeping a lot of men from experiencing full intimacy, connection, happiness, intimate and fulfilling friendships, a helping hand, etc.
