Cloudflare doesn't automatically block Tor exit nodes, they just tend to earn a bad reputation. As a site owner you can decide what to do with that, the basic protection level issues CAPTCHA challenges.
Cloudflare also has it's own onion service, sites can opt in, and Cloudflare's public DNS is also available over it, sidestepping the need to go over exit nodes after the first request.
