How many spaces and circuits are required? And how do you know whether you need 100amp or 200amp service? I was told that if installing a hot tub or pool in the future, I should install a 200amp service, is this true?

Reason: additional info...
The size of the service is determined by a demand load calculation.
The minimum number of circuits is; two 20 amp small appliance for the countertops, one 20 amp for the bathroom receptacles and a 20 amp for the laundry. This is in addition to and dedicated to appliances like electric dryers, water heaters, furnaces, air conditioners, etc. You would also have circuits for general use receptacles and lighting.
