Any CDN worth its salt can run on your domain so that’s not an issue. The issue is that no third-party anything is pointless as links will just change from nyt.adnetwork.com to adnetwork.nyt.com. I’d rather not encourage those kinds of DNS shenanigans.
You’d tell cloudflare DNS “yo put your stuff on cloudflare-cdn.mydomain.foo”. Embeds should be iframes, that is, different webpages, imgur could do the same though yes it’s overkill. Another option would imgur offering an automated API that would allow cloudflare DNS to tell it “here’s a key, please get ready to serve on imgur-cdn.mydomain.foo”.
It can all be handled on your domain without you actually running the backing servers. It’s also insanity.
It doesn’t, but it defeats the purpose of CDN, because your users still hit your domain instead of CDN one and cannot leverage the benefits of distributed caching. Browser cache is bound to a URL, you change one letter and it is invalidated.

What about a CDN for JS libraries?
What about YouTube embeds?
What about images from Imgur?
Why should all of this be handled by me, on my domain?

No. Things being on your domain doesn’t mean that traffic hits your servers.
