I've lived in 9 states and in every neighborhood many people have food producing plants. It's one of the healthiest hobbies you can have.
I love gardening and have a small orchard and have other food plants all around my house, but I still maintain a lawn because it gets my kids outside playing sports, it's a very multifunctional space, and because covering every square inch of my property in food bearing plants would be way more work and time than we have to give. In every home (except Arizona) I've kept at least some portion of the property as grass lawn.
Some people latch on to your idea but then a few years later end up with an unmaintained berry bramble of a yard full of invasive food plants that is totally unusable. Moderation and common sense in all things.
Big factor for me is whether or not either of you have lived rural before.
I worked in a very remote medical center not too far from where you're considering. I needed to send a patient to a hospital for a severe infection one of my first days there. Life flight refused because of winter weather. The ambulance driver came to me and quietly asked if the patient really needed to go today. After I told him yes it was striking to see them strap tire chains, shovels, and a generator to the exterior before leaving. They really weren't sure they were going to get to town that night.
You miss out on many of the benefits of modern medicine when you're in a town of less than 20,000, and you'll need to be ok with driving for hours for specialist care in a city of less than 100,000.
I-80 in Wyoming closes so often for weather that they have permanently installed gates across all lanes.
That being said, an adventurous and self-reliant lifestyle is one of the best things you can do for your health and longevity. If you know what you are getting into and think this would help you thrive, I'd say go for it with the agreement that if health changes you will move back to a city.
