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|
|Node Page Disable (node_page_disable)||✖||✔||2020-11-05|
Adds an checkbox labelled 'Retain /node as an active url?' to /admin/config/system/site-information
This lets you disable the /node page which would otherwise list all published content.
Note it doesn't let you individual disable /node/xxx access by content type - see restrict_node_page_view or rabbit_hole for that.
This is for D7 only - in D8 you go to /admin/structure/views and disable /node there.
