IMO, it is best not to think about AOV as if it has a direct affect on D of F; it does not directly affect D of F. Think of D of F in terms of magnification and f stop, and it is more simple to understand. Anything that changes magnification will change D of F. Once you understand this, you can think of AOV in terms of how it affects magnification, and it will make more sense.
This means same format, same f stop, same location, different lens, and you will have different D of F. Longer lenses shot from the same distance as shorter lenses make things larger in the viewfinder, meaning more magnification. Therefore, less D of F.
Also, same AOV, same f stop, but different formats, and the larger format will have less D of F because it has higher magnification (image is larger on the film simply because the format is larger, even though the spatial relationships are the same with the equivalent FL on the smaller format).
And, of course, same format, same lens, move camera closer. Subject gets bigger, meaning more magnification. Thus, less D of F.
At a given f stop, you can figure out whether you will be getting more of less D of F by making any change if you simply reason out how that change will affect magnification.
And you can definitely get shallow D of F with subminiature cameras such as 110 format or APS-C/H. You just get more D of F at a given f stop and identical composition than you do with 35mm or larger formats.
The cameras that are hard to get shallow D of F with are the ones that have even tinier sensors or film frames than APS-C.
