Why haven't you mentioned Drupal 9? As of February 2022 I've updated all the sites I look after to Drupal 9 (experience: mixed). I haven't decided how to label future version compatibility as D10 will be coming soon as well. The upgrade_status module is superb. You're bound to have issues with composer. Also watch out for a nasty session headers bug with redirect_after_login.
What about sites still running Drupal 7? In short I still recommend leaving them on Drupal 7. Your decision is really if you will gain anything from Drupal 8/9 and for many then answer will be no, and one of the main hassles - apart from converting each content type one at a time, and setting up a new theme, will be recreating all your views by hand, as views can't be automatically upgraded.(1 modules in list)
|Name||D8||Personally Tested||Last Updated|
|Field Permissions (field_permissions)||✔||✔||2018-11-21|
Control editing/visibility of individual fields by role.
As well as custom settings ('create own', 'edit own', 'view own', 'edit any' and 'view any' - all per role), there's a Private setting which gives access to the author and administrator only.
These are automatically applied to views.
Finding the setting: Look for Field visibility and permissions – on the Edit tab, NOT Field Settings.
In /admin/people/permissions there's also a Access other users private fields permission.
