Cloudflare Warp has been more of an issue for a small webapp I run than residential proxies. Because it's a mix of legitimate users whom I guess installed the 1.1.1.1 app and have no idea they're tunnelling all their traffic through Cloudflare, and abusive users. I've never seen an actual CGNAT IP addresses from a consumer ISPs being shared by a legitimate user and a persistent abusive one.
CF seems to end up in the business of making problems worse, and selling the fix way too often. Before this, I had someone try to DDoS a webapp by setting up their own domain to proxy to my backend and running their attack traffic through CF. But that was easy, I could just block CF's IP range entirely as I don't use their reverse proxies.
