Why haven't you mentioned Drupal 9? I will be adding this, but as of August 2021, this site you are reading is the only Drupal site of mine I've been able to upgrade to D9, so although you can check D9 compatibility status of all modules (use upgrade_status, it's superb) I can't speak from personal experience about any of them.

CKEditor Wordcount (ckwordcount) 2018-12-06

d.o. page

Adds word/character/paragraph count to the CKEditor status bar (can optionally enforce a word/character limit)

Configured via Text formats and Editors (/admin/config/content/formats).

Requires the ckeditor wordcount library - example composer.json for that (put this in your 'repositories' section):

        "ckeditor.wordcount": {
            "type": "package",
            "package": {
                "name": "ckeditor/wordcount",
                "version": "1.17.4",
                "type": "drupal-library",
                "extra": {
                    "installer-name": "wordcount"
                },
                "dist": {
                    "url": "https://download.ckeditor.com/wordcount/releases/wordcount_1.17.4.zip",
                    "type": "zip"
                },
                "require": {
                    "composer/installers": "~1.0"
                }
            }
        },

and then require:

"ckeditor/wordcount": "1.17.4",

Patch needed:

(to ensure modules gives browser correct path of plugin.js - if your ckeditor input disappears, check console.log and it's probably that)

The notification module is a dependency.
