Fiber internet provider

With quarantine and now school streaming we are hitting the Comcast data limits (We've come close or gone over the last few months). The kids now spend all day streaming school and the rest of the time on zoom with their friends or streaming content and September is our highest usage yet.

I figure as long as I'm switching providers may as well upgrade to fiber and get a speed upgrade (we have an old slowish plan now).

Looking for recommendations for providers that don't have caps or have reasonable caps (Comcast is 1.2TB limit before charging $10 per 50gb). We currently pay about $80 a month so would also be interested in how much it costs in the real world (just internet, we cut the landline and tv cable cord long ago).

Thanks!
