You seem to have a good handle on it.
Scooters can be easier to ride on surface streets and through parking lots with the short wheelbase (length) and lack of a hand clutch. It is also easier to find a spot to park a scooter than a full size motorcycle.
If you don't ride in a lot of stop and go traffic, a small displacement motorcycle will likely be more stable and comfortable.
There are always exceptions, There are a few scooters that still have a manual clutch and there are some smaller motorcycles that don't need a hand clutch and there are scooters as big as 650cc sold in the states.
I don't think a scooter will disappoint you unless you do most of your riding on the freeway and open highway.
