Migadu, asked about by the OP, has my current recommendation.
@xanlopez.net: Speaking of which, I want to move away from Gmail, but I'd rather not self-host my email. Proton leadership seems pretty shady, and I don't think I need E2E. Fastmail apparently hosts its servers in the US. Any other good options? Is anybody here using Migadu? www.migadu.com
