The Sims 4 Wiki is another site you can search. Often when googling a question, it's going to be one of the top links.

You mentioned using the moveobjects cheat. It can't be used freely without caution. Useable objects need to be reached by sims and are likely to be blocked when you stack objects using the cheat. Thus the confusion and feet stomping. You'll notice green squares when placing things normally. Red squares when you can't. The system is there for a reason. Try rebuilding the kitchen without the cheat.
YouTubers like to build with moveobjects to make builds eye catching but the thing is they rarely ever play test them. When I use the moveobjects cheat it's only for decor sims can't interact with like plants. I never block usable items like appliances, plumbing, comfort objects. I have it turned off when placing those items that sims need to reach. If I really want to risk it then I make sure to play test.
