This is quite interesting and I’d like to know about the reasons as well as how all these are managed, the constraints, and any other annoyances you might face because of this approach. Using iCloud makes sharing things so easy across devices, and I’m not for trading off one bad service for another bad service (am not implying that you are).

If you ever write this up (or have written this up) in detail, please do share.

I use the devices primarily as clients for cloud computing services: IMAP email boxes, Signal, Google Voice, Standard Notes, Spotify, Feedly, ProtonMail, Slack, Mattermost, et c. I find I have relatively little need for "sharing things across devices" that aren't met by the cloud functionality of apps.

The big one I thought I was going to miss: contacts sync. I don't miss it. I keep a phone number list in Standard Notes. Most of the functionality of Signal's "recent conversations" covers this need for me.

I'm setting up nextcloud soon and I understand that can do contacts/calendar sync to iOS. The only thing I haven't found a solution for is email inbox delegation and shared calendars.

You're right that this would make a good writeup.
