Why haven't you mentioned Drupal 9? As of December 2021 I've updated most of 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.(1 modules in list)
|Name||D8||Personally Tested||Last Updated|
|Serial Field (serial)||✔||✔||2018-11-23|
Creates a field with a serial number, so you can have the equivalent of a MySQL AUTO_INCREMENT field for a content type (if nodes are deleted the old serial number is not reused).
Although this only has a dev branch which hasn't had updates since April 2016, it does work in D8.
There's no direct migration path previous versions, but people have written their own migrations.
