I think it's deliberate the fact that they went more copy of the sitcoms instead of making fun of them. Because I think they are going with, Wanda most likely grew up watching American sitcoms and found them comforting. So its like her happy place in a way, life in sitcoms are simple and everything always works out in the end. Unlike the real world.
She's not trying to make a comedy show about American sitcom tropes. She made a place where she can be happy and live her life with Vision. Yes the title is their names but this is more Wanda's vision of the world she wants. She's not a writer, she's a woman with uncontrolled superpowers having a mental break.
This is how she "Invisions" sitcoms, however with her powers she's able to make it a reality. I think most of the neighbors are either Hydra agents or Sword agents that were trying to get to her and ended up being mind controlled into becoming part of her vision. (that's why there are no kids). They keep trying to send agents in and she just keeps adding people to her neighborhood. I also think Wanda is not completely aware she's doing that either. She has some lucid moments but she doesn't want to face that reality so she makes herself forget as well.
We are seeing what looks like an innocent happy sitcom but in reality she's mind controlling a bunch of people and forcing them to live in her fantasy world. If you try to break her out of her reality there will be consequences, like the Vision's boss demanding answers, I think Wanda made him choke and was going go let him die and cutting Dottie's hand when she started asking questions. She spared them now but I think it will only get worse the further Wanda believes this is her reality.
