I'm going to do more research and as I demo the place the best way to go will probably reveal itself. I'll let you know. Thanks

Depending on your goals you could simply strap the exterior with 4-6" of EPS and then cover with siding or whatever finish you choose. Probably simpler and cheaper than simply framing the outside of the walls.
What kind of temperatures do you get year round? IIRC you are in the desert?
Thermal bridging is when the heat is transferred by conduction through a solid frame structure. Like the metal sill plate of an exterior door gets cold so fast. If you put the studs up tight to the 1x10 they will conduct the heat and bypass the insulation.
And you don't need to spend the expense of 2x6 just to get a 6" cavity to fill. You can use 2x4s spaced out using spacer blocks at the floor and ceiling. That will remove thermal bridging from the wood, too.
