There are places in Florida that are no more expensive than living in the piney woods of eastt Texas or in the cottonfields of the Mississippi Delta. But they don't have large populations of winter visitors nor parks on the coast or inland waterway, and will not be golf resorts. They might even be 15 miles from the nearest gas station, 30 from a supermarket. I drive through this part of Florida every time I visit my brother, who lives on one of those resorts we cannot afford. Yet there is real estate 1/10 the value of what is in his development, and a trailer park taking RVs at $300 a month, withun two miles of his resort.
So it is not even Florida vs elsewhere, it is about choosing a lifestyle location that fits your budget. The one thing you cannot readily do in Florida that you can in other snowbird areas, is find public land where you can squat for almost nothing, all winter long. Compared to major metro areas, most of Florida is still pretty cheap living.
