arrive in a new city/country, open Uber, specify in the app precisely where you want to go, choose a vehicle, when to get picked up, etc, track vehicle progress in real-time, up-front pricingThis is actually something we should be a little uncomfortable about. It's a fine example of monopolists at work. The convenience does come with downsides.
I do like it, though, for exactly the reasons you state. If I end up in a country with cabbies who generally have good English skills and aren't out to rip me off, it's fine, and often easier to take a taxi. But you never know until you get there, and that can be stressful. The consistent Uber/Lyft experience is a breath of fresh air after a long flight when you just want to get to your lodging and pass out.

Eh, I'm not convinced. Sure, it's changed, but the general paradigm is the same. The main big change is the mobile boarding pass, seamlessly delivered after checking in on your phone, which is a genuine improvement. (But so many airlines still require you to check in with a human at the airport for international travel.) Print-at-home does come close enough, though, and still means you avoid lines at kiosks or (gasp) waiting for a real person to print you a boarding pass. Some airlines now charge you to print out your boarding pass (because of the availability of mobile passes), and that's disgusting. (I know people who still insist on printing at home, because they've had bad experiences around their boarding passes refusing to load, app crashing at exactly the wrong time, etc.)
Yes, all the airlines have apps, though after traveling a bit in Central America and in the Balkans recently, I've found that some airline apps are absolute trash, worse than having to wait in line for an hour to talk to a person. Most of my digital interaction with the airline is done on my laptop before the trip anyway. Notifications about gate information or delays are useful, but a push notification from an app is not markedly better than an SMS, and either way I always feel like I need to verify on a physical departures board, especially if connection timing is tight.
In instances where my flight has been delayed or cancelled, it's definitely an improvement to be able to rebook in the app, instead of waiting in line to talk to someone, or getting on the phone with the airline (or both, as I'd usually do, to find out which would resolve the problem faster).
I've never used airtags (don't have an iPhone anyway); I've checked bags at most twice in the past 20 years when I had no other choice (my mantra: checked luggage is lost luggage). But even considering that, I feel like all the fuss people make about airtagging their luggage is overblown.
Some airlines have eliminated seat-back entertainment and expect you to use your phone. That's crap.
Meanwhile, as GP has pointed out, security, customs, immigration have all gotten worse. Boarding processes have not improved, food hasn't gotten better, and airplane seat comfort has gone down. I say this not to blame smartphones, but to suggest that there are other, more important problems with air travel that have nothing to do with phones.
