Re natural gas:

- methane escape all along the chain is very problematic climate-wise
- CNG tanks are very bulky and heavy, arguably more difficult to integrate than battery packs
- bifuel gasoline/CNG vehicles are compromised when running on CNG, to the order of something like 20% lower power and miles per gallon equivalent

Finally, dedicated CNG vehicles are a non-starter. See market failure of the Honda Civic GX, later known as Civic Natural Gas. This is most likely because no one wants to pay more for a still fossil-fueled vehicle that has very limited refueling infrastructure and no easy way to refuel at home. (There were some attempts at home vehicle refueling devices but they were similarly failures, expensive @~$4-6k + electricity cost to compress low pressure NG that comes to homes, and only mountable on the exterior of one’s garage due to fire codes, iirc.)

So if you run a fleet in Oklahoma and can fuel up for effectively free from your own wells, sure, convert your 3/4 ton work trucks to that. (Same goes for fleet operators of garbage trucks and the like.) But for Joe Sixpack? No way.
