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)

|Comment Notify (comment_notify)||✔||✔||2018-12-15|
Allows users to receive emails for replies to their comments (or optionally for all comments on a node). Can be toggled by content type (although not by comment type, if you have more than one comment entity). In permissions, you can also control which roles can subscribe. Can also set it so the author of a node also automatically gets emailed for every comment.
I'm using three patches:
I also have a site which uses two comment types; I wrote a patch to turn off the notification checkbox for one of them.
