Today I once again noticed two overtly minor things, that nevertheless go a long way for me: I can queque up "eat", "use toilet" and "shower" and the sim will do it in exactly this order. Whereas in Sims 4 the sim would take their lunch to the bathroom, eat it while doing the business, leave the room to put the plate down and only then enter the shower. Visiting sims will also move to leave my bathroom after finishing instead of lingering in there indefinitely.
This awareness of the sims' surroundings adds a lot to my immersion. There are still plenty of over-the-top situations (like one of my teen sims hula-dancing the ornamental fish as if trying to connect to them on a cultural level - it was utterly adorable), but they happen organically instead of getting forced by design choices.
