ArcCatalog reports a LatLong Bounding Box of:  -180, -85.051, 180, 85.051, which is far beyond the borders.  I am wondering if Mapproxy is caching outside of the county boundarys, or if Mapproxy is caching the correct area, and since ESPG 4326 is disabled, ArcCatalog / Mapproxy is reporting the wrong boundary box extent.

Does you cache use both grids? MapProxy will use the largest grid for the BBOX in the capabilities and global_geodetic is world wide. You should use the coverage feature for you source, if you want to limit the requests to some boundaries. MapProxy won't cache any tiles for requests that are outside of the configured coverage, even if they are inside the grid.
