Yup, it's probably a decent solution for us. We live near some 5G towers at a city park. The population density here is pretty low, but the capacity needs to be high because we have a few festivals in that park throughout the year.

So I'm guessing the 5G offering is pretty competitive, but I'm already in a solid wired service so it's not very attractive. My city is also rolling out fiber starting this year, so my service will get even better and probably cost about the same (my current service is from a halfway rolled out fiber network that good shut down due to political nonsense; I get Cat5 to the house, and share fiber with the block).

I'm sure the are communities similar to mine that don't have decent wired Internet for whom 5G could work. Also, it existing puts pressure on other services to improve (e.g. my ISP started offering higher speeds only after the city put out a proposal for citywide fiber).
