After hundreds of retries I was able to setup the certificate manually through web UI and now terraform resource shows that it wants to change the cdn resource because

  ~ resource "digitalocean_cdn" "bucket_cdn" {
      ~ certificate_name = "needs-cloudflare-cert" -> "correct-cert-name"
        id               = "xxxxxxxx-xxxx-xxxx-8a9d-9e3af0e670c6"
        # (6 unchanged attributes hidden)
    }
