Which of those issues are in place because men are oppressed as being inferior instead of being gender expectations that feminism targets? Meaning: which are a consequence of gender expectations?

High suicide rate is connected to men more likely to have access to guns and because they are less likely to go to a doctor because of gender expectations.

Loneliness is on the rise for everyone. Some studies find more loneliness in women. The idea of "the male loneliness epidemic" is meme that just generates tons of clicks and engagement. It's not real.

For the work place it's again a problem of gender expectations. It's not because people see men as inferior.

So are the next three.

Men are actually more likely to get custody if they ask for it. You have fallen for a manosphere conspiracy theory that has no basis in reality. Women more often get custody because when both parents work, the men's job is respected, the women's isn't. They get automatically assumed to be the caregiver because of gender expectations. The only thing a man has to do is literally ask for custody. On the other hand, a single mother who is expected to do the brunt of the caregiving, can't force the father to take more time with the kids. Simply because of gender expectations.
