We have been testing baikal, and will probably use that.

Another option is https://radicale.org/v3.html

After some initial research, I decided to go with radicale because it was the simplest of the options.  No need to run another web server process w/ PHP and an SQL database.  Installation was easy and for my rusty server admin skills I managed to get things up and running in an afternoon.  macOS/iOS/iPadOS clients seem to generate a bunch of authentication/authorization errors but they still work.  Hopefully won’t take too much work to figure out a workaround at least.  But I digress - my issue has been logged in GitHub. :)

I want to thank everyone who worked on the Darwin CalenderServer project over the years for offering a free and relatively easy solution for a long time.  Your efforts are greatly appreciated, and I learned a bunch from dabbling with it!
