I really enjoyed sanity.io a year ago. It had the best data structure flexibility by a mile, with the ability to have multiple user draft states and merge conflict resolution.

Other Headless CMS felt restrictive, with shared drafts or the requirement for all published items to have changes go live instantly.

Once you're set up with your schema, the UI is easy enough for non-developers (and you can customize it for them if needed).
