Sadly, you don't even need to go very far out of some major metro areas in the United States to find ZERO options besides either, as you say, 'unlimited' cellular data with intermittent service, or capped satellite with latency too great for anything like video conferencing. When I say zero, I mean not even DSL is available. Even options like "Fixed WiFi" don't reach a lot of properties due to hills and forest cover, and even if they did they'd also be capped similar to satellite.
