I agree this data should be free and easy to access from the government.

Personally, I've found weather.gov APIs hard to work with. There's no geocoding included, and you can't even use lat, lon directly. But the bigger dealbreaker is that I have about a ~10-20% success rate querying any given endpoint, where sometimes I just get "An unexpected problem has occurred." And this is an automated twice-a-day query, so I don't think I'm hitting any rate limits...

You can use lat,lon with the points endpoint: https://www.weather.gov/documentation/services-web-api , then properties.forecast and properties.forecastHourly endpoints from there to get daily and hourly forecasts. I don't have enough experience with it to comment on rate limiting, though.
