I had a company car the last ten years of my working life, and it kept the miles and salt off my 2014 Tahoe. I did not know about GM's Crippled Cylinder System when I bought the truck new, but intercepted any early damage by using an OBD module defeating CCS for nearly all its 66,000 miles. Eventually I will have the engine converted over to normal, without any CCS.
I would recommend against your buying a current model GM because they persist in using CCS, and it now is even more difficult to defeat. If you do buy a new or late model, budget enough additional to pay for parts and labor to remove all that crap and get the engine on a more reliable path to a long life.
My 2014 was the last where a buyer could avoid most of the dashboard display electronics, another failure point long term. No TV screen, no tracking by Big Brother, Mr. OnStar, no robots "helping" me drive or reach a parking space. I don't know if that's important to you, but layers of electronics all represent something to fail during long-term ownership. Warranties won't help when components are no longer available. And I really don't like the dead feel of being insulated from driving the car myself, or having things beep, whistle, or talk at me when a microprocessor disagrees with my operating inputs in any manner.
I concur with those who disapprove of anything from the foreign-owned Stellantis. Chrysler and its descendants have not found a good home, and what's left has problems with quality control and design shortcuts. Subaru has solved its oil burning problems of a few years ago, but their vehicles might not be big enough for your sense of crash comfort. I happen to think a more nimble vehicle like a Subaru can best avoid a crash in the first place. There's a large Hyundai to consider. The Koreans have been about 10-15 years behind American made Japanese models, and I think systems more simple mean greater long-term reliability.
Good luck finding a satisfying 6 or 8 cylinder. We also were fortunate to get the last 6-cylinder Acura before they reverted to their earlier 4-cylinder turbo that was problematic. Me, I'm just glad this 2014 Tahoe came along when it did. For you, it may already be too late to meet your criteria. I certainly don't see anything out there I would want, and now that I've been retired, I don't have to worry much about avoiding vehicles loaded with "features" no one asked for.
