LOL Winter Haven, Florida is definitely the south. I lived there for 12 years or so. It’s a small town, right in the middle of the state. Lots of agriculture, citrus, phosphate mining in nearby Bartow, and it is a very long way from Miami or Disney World or beaches or whatever it is non-Floridians think of when they think of Florida.
It was a nice place to grow up, frankly.
Winter Haven...Lake Wales....Frost proof....Haines City
All Dixie
Frankly most truly rural Florida is quite southern
From Everglades City to Clewiston to Okeechobee up 27 and 41 to the panhandle
The Mouse and Cubans and Snowbirds changed it but when I lived in Miami...80s....there were still southerners in MyAmUh proper....
