I wouldn't lump WAFs in with standard firewalls.
Perimeter firewalls are your first line of defense against intrusion, and segment your network based on need to access other networks. Microsegmentation firewalls ensure the only intra-segment network traffic that is going on is approved traffic. Devs need to supply source/destination IP addresses and ports to allow traffic.
Web Application Firewalls (WAFs) perform an inspection of HTTP requests to halt attacks on web servers.
I'm trying to craft a point to address this simply.
Looks good to me! I saw you mentioned CloudFlare as a DDoS mitigator, they also provide a WAF service, which would be good in the HTTP traffic section.
Got it, thank you!
