Location matters. Cheyenne with a population of 65,132 is large enough to expect good medical care (though I didn’t look this up - you should!), and is only a few hours drive from Denver. It is also small enough that you can live practically in the city while also being in the rural exurbs. Something like this may be a good compromise depending on exactly why you want live in a rural area and what you want. There are other “cities” with good enough medical care available (and don’t forget to look just across the border at other states). Maybe you can find a best of both worlds situation.
That said, you should be thinking about what next. Because at your age things can go downhill fast. You need to have good long term care for a nursing home (make sure it is good - you don’t want to be in a nursing home that stinks like a sewer system so don’t buy on cost). Make sure you have a plan on how and where you will move “back” when/if life forces it on you.
Remember farming/ranching is dangerous. Make sure you understand all the safety processes and don’t cut corners. You are doing this as a hobby so feel free to lose money or hire out things.
That said, staying active in old age is your best way to get and stay health such that you can do those things. Those who sit around on the couch after retiring tend to die quick. My great-uncle ran his North Dakota ranch until 95 and only stopped because he couldn’t care for his wife’s Alzheimer’s and run the ranch, I believe the activity is part of why he lived so long.
