I can't say I see a clear pattern where physical strength is directly correlated to extreme gender segregation. The extremest male dominated profession is tile floor constructor (ie primarily bathrooms). Second was mechanic and third is tinsmith. The extremest female profession is indeed midwife, but it is then followed by dentist nurse, followed by pediatric nurse, followed by secretary in hospitals, followed by district nurse, followed by therapists, followed surgeon nurse, and we are still at 90%+ professions. After this comes a bunch of specific education and social security professions.
The common theme I would say is that female dominated professions are focused on social environments where a person can feel that they have a real impact on others in their local area, while male dominated professions is focused on profession where a person work mostly separated and alone, and where the work don't general cause a major impact in someones life. In return for not having those social benefit and status, they generally also have higher pay.
Tile floor constructor and dentist nurse, with both way over 99% gender segregation, are quite strong data point. You don't need massive strength to lay down tiles in a bathroom, nor is dentist nurse a very "children" focused profession. Why do those two profession so extremely repel each opposite gender?
Don't underestimate the tiling - iirc it is the job with the highest risk of becoming physically unable to continue working. (edit: "tiler" seems to be the job of tiling roofs. I found a list in German that puts it at 2nd highest risk, after scaffolder. Tiling (presumably) bathroom floors is at position 7 on that list of jobs most risky for becoming physically unable to continue working).
Looking at the male jobs in your list (the bottom of the list?), it seems to me there are a lot of them with high physical risk. For example fire fighter, or wood worker (? "forest face mask" - not sure what that is supposed to be, but if it is woodworker, that is the job with the highest lethality). Concrete worker sounds quite physical. There was an article about grip strength on HN which mentioned mechanics might have become weaker because of automated tools, so that seems to have involved some physical strain at least historically. Plumbing might actually be rather strenuous, too?
Anyway, I don't claim to have all the answers, just theories. Physical strength would of course not apply to all job segregation, I mentioned other factors in my previous post.
