Let's Encrypt is a certificate authority and provides certificates and so it would be end-to-end. However, CloudFlare is not end-to-end unless the server already supports HTTPS.

I wouldn't call CloudFlare end-to-end encrypted. They see the plaintext, independent of whether communication with the backend is encrypted or not.

CloudFlare has a detailed explanation of the various options[1].

HTTPS isn't supported if you're using GH Pages with a custom domain.
