A CDN doesn't necessarily have to perform a MitM. We really need more nuanced terminology to distinguish the various approaches.

Right, but practically speaking all CDNs are MITMs. If you're against cloudflare you should be against cloudfront, akamai, etc. as well.

Ideally yes, the TLS termination does not need to happen for caching purposes. Challenge is that in practice every business wants to be sticky and try to provide more functionalities which do require TLS termination. Most people either trust CDN's or they do not understand MitM so it does not concerns them. Plus they are getting certificate management and DDOS prevention capabilities.

How would they cache and serve responses without decrypting the traffic?
