While the aggregate stats are good to check, what I've found in working on
this stuff is that it's only a few origins that will get you. I'm sure
Cloudflare has a lot of data. But you can map this to ~43% of the web being
Wordpress, hosted on AWS, Hetzner, etc.

The ones that get you are important ones running obscure infrastructure,
like banks, government websites, and corporate portals.

thanks,
Rob
