Look at a m4/3 camera too if you want a small package (ie. still small with camera and lenses)
Panasonic G series is pretty good for the price.

There is also the Olympus m4/3 cameras.
m4/3 cameras already have a good selection of different focal length lenses to meet your needs. (pretty small too)
There is no real bad camera nowadays. Other options are also ok, just make sure the other mirrorless options you are considering has the lenses you need and interface you are comfortable with.
