Does 1.1.1.1 send ECS info to Cloudflare’s own nameservers? More generally, does 1.1.1.1 in any way treat Cloudflare’s own nameservers in a special way and send it information that it doesn’t send to others?

If the answer to these questions is no, then Cloudflare’s reasons for blocking ECS (ie privacy) carry weight. Otherwise no.

When using 1.1.1.1 as resolver Cloudflare has your full IP. So they can fully track you.

ECS doesn't even forward the IP, only the /24.
