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)

If you only need a small amount of CSS, or want users to be able to directly edit it through the admin UI rather than creating a theme or module.
Caveat: doesn't work for admin themes (at least on D7)
