Just like parent poster, there's a few things I pay for, and those are Kagi and Fastmail :)

Fastmail is... FAST. The page refresh is basically instant, and the UI is super-snappy, well refined and something like 2026, while Gmail hasn't changed in... 15 years? It supports a lot of features (identities, masked addresses, ...), not to mention that I can have my domains properly hosted on it, for 5eur/mo.
