The question asked is a really slippery one. I will reframe from what I would normally say on this subject.
I will say this, as an X-Arizonan, I hope to never set foot again in that state. Point I will stress - be careful of what you wish for, it may come back and bite you square in the butt.
At 69 years old - you don't want to go to all the work, and it is a TON of work to relocate and then later severely regret it. My friend did that when he moved to an area S. of Reno NV. He's 73 and pretty much stuck in a place that has changed and not to his liking. Also, be careful what you read on all these "Greatest Places to retire or live in" articles. Most are total BS. I read and studied for a long time before I retired. I wanted to get out of Scottsdale AZ and live in the smaller town of Prescott AZ where we had a second home. 6 months is all I could take. I had to get out of there - went to back where I was born and could not believe how different it was than I had imagined over the years. 5 trips and all the different seasons to see if it was the "place".
It's a big deal to move, at your age of 69 it's a really big deal - give it a lot of thought, research, and investigation. No one can tell you the best place, so just take it all as info, to research.
Things change by the influence of who is moving in, everywhere...
Many changes and big changes are happening, and many states once considered decent, have gone to crap.
Also. warmer is not always better. You need to find a good compromise. Do not forget humidity, wind, rain, and snow as things to give consideration to. everyone has different levels of each they wish to deal with. There is NO perfect place, so compromises have to be met. Deal with a little of this or that to get this or that. That's the weather part, political views, regulations, control, and governments - that is a whole different deal.
In my opinion, the Midwestern states are the friendliest people on the planet and seem to be some of the only ones with any common sense and decent values. You have to experience it. It is like a night-and-day change from 80% of the other states
Hoping to not offend others, but that is my 2 cents on the subject.
