Unless you want a good HTTPS configuration. The output of https://ssl-config.mozilla.org/#server=nginx is significantly longer than the one for caddy.
The correct thing with Caddy is to _not configure anything at all_ for TLS. The defaults are the correct thing to use. If you override the defaults, then you're more at risk of bitrot due to not remembering to update your own config. Let Caddy (and the Go stdlib, really) choose what's secure.
