I am making a couple of frames, I am going to use 5mm dominos.  2 dominos on each joint A-F in the attached drawing.  My question is should I use the narrow setting on both sides of the joint or narrow on 1 side and medium on the long side.

It looks like you are doing a style and rail style assembly.  In this application, I have used narrow setting on both sides of the joint with good results.

 
I make all of my Domino joints with one side narrow and the opposite side wider. I get wiggle room to ease the pieces into perfect alignment.
 
I do things a little different I guess. I have a 700 (with bit adapters) and always cut on the narrow setting. They line up 99% of the time and if one doesn't, I simply keep it on narrow and shift my XL TK the left or right of the center mark and cut again. This has worked for me since I got the tool.

Thanks for the suggestions.  I think I will go with the narrow setting and if I run into an issue, then I may switch to the middle setting.
 
I've built some storage boxes and fence modules for the backyard with about 400 sipo dominoes in them and every one was cut on the narrow setting and fit perfectly. You just want to make sure your fence doesn't shift on you and that you think through where you reference from. As long as you use the correct reference surfaces the Domino will make repeatable work of the mortises.
 
So I was doing some test mortises and that led me to a potential unsafe operation.  I was using the domiplate, which I always use, but think I need to do them without.  So this leads me to a new question if the fence height setting is 16mm, that should center the mortise in 5/8 inch material, correct?

No, the fence scale is actual so that would put the mortise at the bottom. The depth setting gauge is calibrated to center on the given number. Setting depth gauge to 16 will center it.
