on the topic of calendar+task management, one component I'm still missing is a desktop #CalDAV solution which either does both, or is composed of two apps which do #calendaring and #tasksorg tasks.
I believe my Android solution will work for my needs, but it'd be better to be able to update both calendar and tasks from desktop too, especially if I ever lose access to my phone.
the issue is that CalDAV support is rare and CalDAV-with-proper-tasks is rarer.
the user who made that post has tried more desktop apps than I have, and found most of them wanting as I did.
as of my last investigation, Thunderbird and Kalendar had showstopper issues, and a couple web apps I tried didn't do what I needed.
anyway, I have a few tabs open now with some candidates to look into, so maybe I'll figure something out this time around (I've been down this road 2 or 3 times over the past handful of years with no joy on desktop)
a bit more on why this is such a mess, which to some extent has devolved into "$client is only guaranteed to work with Nextcloud's CalDAV implementation" situation:
