For me a household of 5 is kind of small. I prefer 10-14 sims (no pets). I've gone up to 24 before, but my game tends to run into Error Code 12 with that many in the household. :'( Usually I have one main couple and they (somehow B) ) end up with tons of kids. I picked this option because it's the closest to how I play.
Option 2 kind of fits though. I pretty much micromanage everything and pause the game frequently to figure out what everyone is up to and decide what they are going to do next. I often keep more focus on one or both of the parents, but not so much I ever really ignore the others.
Option 3 kind of fits too. When I need a break from managing ~14 sims I'll either send some off to a venue (frequently the festival) or take a subset to university or OL.
Option 5/6 also kind of fits. I do regularly move out the eldest children, but I don't play rotationally.
