So do I. During lockdown a french hosting company set up bbb instances on their infrastructure, and the experience was really good (they even activated the “join with your phone” feature).
Zoom and Gmeet are usable (usually calls are stable and quality is ok) but closed-source shit, and I had a lot of stability issues on public jitsi instances (though I never self-hosted).

I’ve tried opentalk for the first time a few weeks ago (it’s included in my email provider plan) and it worked fine.

Running on that VM, I really enjoyed Flight of the Amazon Queen a few years back. Warning: it’s an oldie containing lots of sexist moments - I’m not sure I would enjoy it as much today.

I second that, been using mailbox for the past 6 months and it works like a charm. You also have a todo tool on mailbox that I think synchronizes via Caldav too, but I don’t use it so I don’t know how it compares to todo.txt

Proton has a nice UI and works well (I’ve used it for two years before moving to mailbox.org) but as of 6 months back, I was unable to make it work outside their walled garden. You can subscribe to proton calendar with any other calendar app, so you can read your calendar via caldav, but I found no way to edit it other than using their app.

I would recommand Proton for a lot of reasons, but if having a caldav calendar matrers to you I don’t think Proton is a good option.

I use Olaucher and it works great for me. You just long-press any app in the drawer and you get the “Hide” option.

It’s of course FOSS, I use the F-Droid version.

It’s entirely text though which I like, but maybe that doesn’t fit your needs - no icons and no widgets.
