You disagreed about my SharePoint online knowledge, but I’ll leave that now as it went way off track :-)
Now on to your questions about giving your 10,000 site admins this functionality. It’s fairly simple as stated in my original post, as you already have the site collections look in to (or speak with a developer within your team) about content types, site templates, search queries (or rest api) and how to package this for easy deployment so you can make it available to your site admins, no matter the size of your organization you can make this available to everyone in your business in a relatively short space of time, depending on the speed of your developers 😉
I will congraulate MS they have done a great job with this functionality making this easier to understand for companies that don't have developers or experts in house.
