The main benefit for me is the integrated SSL certificate generation without needing to configure separate certificate infrastructure or Letsencrypt/acme. Also, Caddy implements a number of best practices by default without needing to specifically configure them, e.g. redirecting HTTP to HTTPS. I do still manage a couple of fairly complex Nginx configurations, and I don't really see any benefit to retrofitting Caddy into that kind of scenario. But for a new deployment, I'll almost always reach for Caddy in the first instance.
