As a native Phoenix grower, I can supply you with some advice, but not much. Your best chance in terms of CPs are certain Sarracenia grown in shade (possibly S. minor), Drosophyllum as they are quite hardy in dry climates, certain high tolerence Nepenthes (ie. N. ventrata), pygmy drosera (sundews), and maybe some butterworts. VFT's tend to get overwhelmed by the intense UV, and heat, acclimation or not. I have even tried VFT's in shade, and it still doesn't work out too well. I will make another attempt in the coming months, but most of my CP's currently are grown indoors through the West or South windows with good results. Trying to grow in this desert heat is just too much; however, if you had a pond or a DIY bog, you might have some great results.
My experience with sphagnum in summer temps has been pretty bad. It tends to dry out super quick in this heat, shade or not. Water evaporates very quickly, and water trays are pretty unsuitable; you could somehow do a DIY tray that helps evaporated water collect at the top, and fall back down, but my try at it was decent. Overall, it didn't accomplish much as the moisture would evaporate out the soil. Natural shade, and shade cloths are your best friends out here.
I grew in Avondale as well for a bit, and I find their weather to be a bit more on the windy side at times, especially in a 3rd floor apt. It's a lot more suitable for CP's out there than in Phoenix, however you're still going to be dealing with the triple-digit degree weather at some point.
