Gutenberg Editor already maintains the parent-child relationship when you select a category. So the child doesn’t move at the top in the category meta box. So this plugin isn’t required if you’re using the Gutenberg Editor.
Categories in Hierarchical Order plugin applies to WordPress Classic Post Editor only.
This plugin contains functionality to let you maintain default hierarchical order of categories when you select and save them for a post in your WordPress Admin Classic Post Editor.
The selected category/categories, to which a post belongs, are by default pushed at the top in the Category tab while saving the post. Whereas activating Categories in Hierarchical Order plugin will keep the position of selected category/categories unchanged as per their parent/child relationship.

Categories in Hierarchical Order

Does exactly what you expect from this plugin. Nice!

Works great!

Does exactly what should be the default option in Wordpress, great! Sorely needed if you have many categories (possibly with very similar names) and rely on a complex hierarchy.

Great!

Perfect

Why is this not part of the WordPress core yet? This plugin fixed my ugly looking category structure! Thanks guys!

Brilliant!

Must use Classic Editor plugin – Add to my list of gripes with Gutenberg that it uses the REST API to display the categories, adding nothing to the categories box for the user while rendering the wp_terms_checklist_args filter useless. If you don’t already use the Classic Editor plugin (installed more than 5 million times to date), you’ll have to use it for this plugin to work. I’m looking for a work-around…
Does your list of categories go on and on, making it difficult to scroll to and find what you need? This plugin will collapse groups of subcategories into expandable submenus, which you may open and close as needed, cutting your category list down to a manageable size. Submenus with checked categories are not collapsed (but are collapsible), so you won’t have to hunt for them.
Thanks to scribu for the code from his Category Checklist Tree plugin, which prevents the breaking of the category list heirarchy.
This plugin works with post categories and WooCommerce product categories too. According to users, it works with custom taxonomies!

Collapsible Categories in the Dashboard

In the Dashboard, collapses sub categories into hidden submenus that can be expanded and collapsed.  Keeps selected categories visible.
