The new iX 60 has more range, but you probably don't need that nor the extra power. The iX 45 seems to better suit your needs, is cheaper and you can option it with air suspension. The iX is a fantastic car, I don't even have air suspension on mine and it's still plenty comfortable and smooth. Not sure where you are in AZ but an underrated feature here in the valley is the IR reflective glass on the windshield - of course you can remote start climate control but if you forget, the cabin in mine in the dead of summer is hot, but not painful/burning. It definitely helps. I'd for sure lease again, you can usually get decent deals if you look around a bit and are a good negotiator, else you can look up a lease broker to see what they have.

I do have to say the Cadillacs intrigue me but I know GM at least for a while had some issues, they might have been resolved now. No Apple CarPlay or Android Auto if that matters to you. The Optiq is a fair bit smaller than the iX, the Lyriq is closer - again if that matters at all. If ride quality is important I'd say the Optiq may be a bit harsher just by virtue of wheelbase difference, but I have not been in one of those yet.
