Mail has been a cloud service since forever, but since I got my work mailbox that can't just be forwarded to main, I use an app. Geary seems to be almost exactly what I need UI-wise, but they do not support 2FA. Funnily enough Microsoft says it will replace Mail with bloated Outlook, so bad decisions are everywhere. If you read to this point and wanted to say "but on Mac" - that one killed itself for me by disallowing iCloud login in Virtualization Framework-based VMs and by extension any dev tools that require it. It also disrespected me as a user by not bothering to say that outright and wasting a couple hours of my time chasing "Something went wrong" around.
