This doesn't exactly answer your question, but I can add some perspectives.
I am semi-retired, working on a contract basis. I do mostly self directed software work, so I don't really need to be online at a particular time except for meetings, and those are mercifully few. I've been remote for the past year.
So I was allowed to set my own schedule. I've been doing TWTh, with 4 uninterrupted days off, FSaSuM. I try for 8 hours the days I work, but it depends on the work whether I achieve that. Sometimes I attend on a M or F for a meeting, or if I need to make up time or meet a deadline.
I hadn't really thought about working weekends, since mostly nobody cares when I work. But it is handy to have others around to bounce ideas off of, or to respond to my emails (sometimes

). Also my personal events tend to cluster around weekends or evenings since those are the times other people are off.
So I guess my need for social connection (such as it is during the pandemic) drives me to maintain a fairly traditional, if shortened, schedule.
