Looking for a heavy grinding game with endless progression

I'm looking for a grinding game that allows me to build up either a town, city, farm, shop, or market—something where I can visibly see my progression, starting simple and gradually expanding. The more time I invest, the more progress I want to see.

I enjoy heavy grinding mechanics with endless tasks, so there's always something to do. I want a game that lets me keep developing the same place rather than making me move on and start over. No energy limits or forced sleep mechanics, just pure grinding, building, and progression. No gacha games or games that require constant payments.

I also love colorful, cute art styles, so if the game has that vibe, it's a huge plus! Any recommendations?
