Lots of great tips and suggestions--thanks so much everyone!
Sealants and coatings have been on my radar since moving here, although I had no idea that my "go-to" carnauba waxes wouldn't hold up in this environment. I've never used sealants or coatings before (aside from Sonax BSD, which isn't a full formulation), but I need to look into this further. I've been really impressed with Sonax products as of late, so I will probably try PNS first. I also reached out to them directly regarding my problem and they suggested CC36 Ceramic Coating followed by a PNS topper every so often.
I've also been considering pressure washing. I don't know if that'll work as the "only" washing solution, but it would be nice to be avoid touching the car entirely. One of my biggest gripes about the rinseless washes is that they don't wash away the dirt and grime that accumulates in the crevices and window seals. Here in the desert, that's kind of a big deal...

Has anyone had experience with Sonax Spray + Seal? If it's effective, it seems like a great workflow for pressure washing. The ONR/pressure washer process suggested by ducksfan sounds like a really interesting approach, too--I will have to look into it further.
To answer Eldorado2k's question about towels, I use a variety of Cobra MF products for specific purposes. Guzzler for drying (after a water blade), Gold Plush for door jambs, Supreme 530 for waterless washes, and Super Plush for waxing and buffing. I use their Waffle Weave Glass Towel for glass. I also have a separate set of MF towels for wheel duty, which are washed separately from everything else. My washing routine is the same I've always done: a little detergent, some vinegar in the bleach compartment, hot wash, cold rinse, and medium heat in the dryer. I think the hard water is causing a problem with this regimen, too, as my towels have been super "sticky," grabbing the surface and leaving a ton of fibers on the paint and glass.
So, I bought some Chemical Guys Microfiber Wash Detergent and some wool dryer balls. I haven't tried it yet, but I'm hoping the soap will neutralize the hard water and the balls will eliminate the static cling I'm experiencing. I also expect to see a big difference with washing towels when I get my water softener installed at the end of the month (not to mention an improvement in the regular laundry!). The DI stuff will come a few months later, but that'll only be used for washing cars.
swines, I gotta thank you for describing your detailing process, especially as you also live in NM. I think the big difference is the product choice (and the number of applications of different products). I've been using the traditional carnauba-based waxes and toppers, but it looks like it's time to step up to something a bit more advanced and durable. Your comment about the UV relationship to altitude makes a lot of sense. I live at over 7000 feet, so it's quite different than sea level. And the sun, wow... just constant. Not used to that! Can you share which synthetic clay bar you're using? I've tried the bucket method and my bars typically deteriorate quickly compared to just spraying on the QD.
Again, I really appreciate the response to my initial post. I have a lot of great ideas to try. I'll continue to report back as I make progress and determine what works best here.
