I think you are asking the wrong questions.

Commuting sucks, avoid it if you can. You have weather to worry about, maintenance, and seats available.
If you can’t avoid a commute, the flight time is the lowest priority. Once you have a seat on the plane, I wouldn’t care about a 30m or a 4h flight. You can read, nap, get stuff done ect.

Company commuting rules is a big factor. Then I would say how many flights a day. That can usually mitigate wx, Mx, and seats if there are enough (and you have protections).

You might have a 1h flight but 4-6h in between flights. Or a 4h flight, but every 1-3h between flights. I would much prefer the latter.

Or yes, a 1 leg commute vs. a 2 leg is about as comparable to no commute vs. a 1 leg.
