Another piece of feedback: It’s scary to consider using such a crucial piece of software in production when documentation is referred to as “sort of deprecated” and “slightly outdated.”

Because that's the old documentation, from early betas of Caddy v2.
The official documentation at https://caddyserver.com/docs/ is up to date, and not deprecated.
That blog post is pretty old. We do have a current upgrade guide here in our docs: https://caddyserver.com/docs/v2-upgrade
We also have a (sort of deprecated) wiki with some (slightly outdated) high-level improvements listed: https://github.com/caddyserver/caddy/wiki/v2:-Improvements
