there's the town building

Which consists of placing a single object in very limited locations, and then grinding money to buy it.

and new shops and buildings you can create

A very limited number of them, most of which appear automatically over time and with usage, and is not something you actively "do".

and all the classic furniture gathering, and house renovating you can do.

Which doesn't take that much time out of each play session as a limited number of furniture items are available in stores at any given time, and villagers rarely sell you anything or give you anything.

Those things are not major aspects of gameplay, you don't open up the game and "do them" except collecting furniture which takes a few minutes each day and that's it.
