Proton Mail says Outlook for Windows is Microsoft's new data collection service
I have tried several, and liked none of them. I'm currently on Geary, but it's lacking in functionality, and it has things like search results being a bit different upon each of my searches. Starred messages cannot be shown on top. Eyeroll.
I think Evolution and Thunderbird are the top contenders, and of the self-hosted ones, Roundcube.

Open source email pioneer Roundcube joins the Nextcloud family
The GitHub issue talking about this [1] is such a mess too. Maintainers closing the question with a vague non-answer, deleting comments left and right, etc. Sounds like someone stole the money and everyone is either complicit or too embarrassed to admit that it happened.

Universal Inbox / Email Client
You could try a standalone email client like Mozilla's Thunderbird, or if you're experienced running a web server, you could check out something like Roundcube. I suppose you could even run it locally if you're familiar with PHP and/or Docker.

Thunderbird 115 Supernova Preview: The New Folder Pane
What I really miss is a "web companion" for Thunderbird, basically something like https://roundcube.net/ or https://www.horde.org/apps/webmail, but a bit more powerful and with better UX. I'd like to use a Google Addressbook within such app, for example (there is a completely outdated plug-in for RoundCube). Another important thing would be powerful and fast search.
