I would say a Shetland sheep dog.
But all the things you named are possible in any dog you get.
Shelties are fairly easy to train and willing to work, they are good guard dogs and family dogs.
They do require some brushing out with the longer hair, but other then that they are good.
Any dog you get need exercise, some of the smallest dogs can walk a long ways and still be bouncing off the walls when you get home.
I wouldn't look into a whole bunch of designer dogs because you will end up paying a lot more with not a whole lot of health guarantee and not so good bloodlines.
I hope this helped
