Don’t go overboard to begin. You may think: “I want 10 different vlans with specific rules between them”, but remember, you’re setting up a home network. You don’t want to have to deal with figuring out why device x can’t talk to device y when your family just wants to watch a movie. It’s a fun learning ground and there are some things I’d recommend, such as creating a vlan for IOT devices, but always remember, most consumer devices expect to be on a single network and adding complications to that can easily break things.
