I don't see anything wrong with putting one on an outside wall. If there was a fire the center usually falls in quicker than the exterior walls. That way you don't have as much of an oven situation around the safe when everything falls in around it. It may also be the cooler part of the fire in that case.
KABA/MAS X09 or X10 are fantastic locks and a lot of the time the $1300 investment for one cost more than the container itself They also have their own unique set of problems.
If it is electronic, anything with batteries outside under the keypad is better. S&G is what I personally like best for ease of service if needed. Good Mechanical locks all meet UL Group II standards and are all about the same from a user or service standpoint.
Concealed hinges only allow a door opening of about 120* where exposed hinges will allow a 180* opening. Either of them are dead pinned on the hinge side so you can't cut the hinges off and enter.
personally I would steer away from locks that are electronic with some type of additional key override feature. For the most part they are imports and don't always have the same footprint as standardized locks for most containers.
YMMV
