Worth noting that a surprisingly common amount of sites have other sections of their site which are not routed through Cloudflare. Look for instances of DNS records like this:
admin.example.com
Such a record is usually not routed through Cloudflare because the last thing a webmaster wants is to solve captchas for their own website. They don't however care much for their visitors if they're subjecting (possibly a substantial amount of them) to captcha solving nonsense.
The content in the non-cf sections of a site can still be accessed because the webmaster is lazy and didn't care to check if a visitor can do a DNS DIG on all their DNS records.
Or you can simply use TOR pluggable transports to pretend you're Googlebot, and also hide all your traffic in Google-like traffic.
I would reserve this for rare cases as there are people in censorship prone countries who really need this bandwidth :)
The pluggable transports are for connections from your Tor client into the Tor network, not connections from exit nodes to the rest of the Internet. Cloudflare (or any destination host) would still be able to detect your connection as originating via Tor.
There are innumerable ways infact to spoof the fact you're not using TOR to a website, and you can read up on these in the TOR documentation.
Ideally you're looking to use TOR as the first hop, and then you dial into the wider Internet with a VPN, or as I mentioned: Using various Google services to camouflage traffic instead of a VPN. This is where pluggable transports come in, because Google doesn't like TOR, so you want to choose how you're connecting to Google, and get to traverse the TOR network to find an optimal route.
While I agree that you can mask your exit from the Tor network via an additional proxy or VPN, that's not the role of pluggable transports. They're only for connecting in to the Tor network, not out from it.
