Traefik solves some problems. Envoy solves other problems. Caddy, I can't seem why to use it but I am not familiar with what capabilities it comes with. There are other proxies as well especially in the Go community. We use nginx. If the features you need exists in nginx I would say there is no reason to switch it out. From a holistic point of view there is only very small performance gains in this area.

I would say Caddy is aimed at small to medium companies. You have a web app/site, no dedicated systems admin and you need a reverse proxy that does the right thing out of the box without you having to learn what the right thing is or how to configure it. Basically going from zero knowledge to a working setup can be done in under 30min and it will be safe.

Ok, fair, we use cloud products in those cases. Nginx, depending on what modules that are used. Like Openresty and so on can be complicated. But there are plenty of people out there that knows how admin it.
