Site: (Site Operator)
Looking for a specific website or pages associated with it? Tell Google what site you’re looking for by using Site Operator.
For Example: Search for Site:backlinko.com This shows all the pages of the website Backlinko.com which are being indexed in Google.
You may replace backlinko.com from any site address you might wish to search and obtain all of its indexed pages.
It saves you time to check out if the site is indexed or not and also, if yes, how many pages are being indexed of that particular site.
Quick Tips:
Modify/Experiment the Searches in Site operator and make most of it.
For example; Site:.edu SEO
This will give you all the sites of .edu url having used SEO keyword.
-Site: (Minus Site Operator)

If you wish to find all the mentions of your site on the internet, simply make use of this operator and enjoy surfing!
Your examples are excellent, perhaps a bit more detail on some (eg Cache) as they are a bit lean, but that could also be the topic.
Would the results be better using duckduckgo.com rather than Google
Look forward to part 2
