I'm sorry if this has been asked before, but do the different spouses have different preferences? Are certain people better at certain things or is it solely based on how often they do a certain chore? Do they ever stop having the "meh" yellow face above their heads?

They do have things that they are "good" at, but this just affects how well they get the chore done. They get better if you tell them to do things they aren't good at. For example, my wife was Kathy, who isn't good at watering, but that's what I wanted her to do. At first, she would miss a few squares - but after a while she would get better and never missed any squares, even in the Farm plot which has 200. And that yellow neutral face is always above them. It's just the "working" symbol.
