I used Verizon 4G for years about 20 miles south of Tulsa. Switched to T-Mobile (and 5G) recently to save money. T-Mobile also has a dedicated 5G home internet that I haven't tried.
Our power company recently ran fiber to most of their customer base. It's available to us, but we have a lot of other things we need to sort out with the house before we mess with that.
If you're in an area covered by TDS Telecom, you may or may not be able to get either fiber or DSL.
If you're in the area covered by Bixby Telephone Company, their broadband coverage is supposed to cover just about every customer they have, supposedly.
Terrestrial wireless is a thing that I never looked into seriously, but I know it's an option that some people go with.
