Good resources for setting up a domain name to a local Caddy instance (piefed.social)

I've been using Linux for decades, I've worked as a software engineer/architect/sre for around a decade, but networking has always been my biggest gap in knowledge.

I have a local server, I have caddy spun up, a glinet router running their version of openwrt, and I have a domain name purchased through porkbun.

I am looking to setup "local.domain.com" to point to my local server, ideally without exposing it publicly, and enable devices on my home network to be able to access it from that url. Id also like to be able to access containers running on that server by something like "searxng.local.domain.com" or "local.domain.com/searxng" aka without using the port suffix. Id also like to enable https.

I have read so many guides that have fragments of what I need, but nothing that ties enough together to get it working. And with all the options around different domain registers, let's encrypt, reverse proxies, etc, im struggling just a bit.

Are their any guides (prefer text over YouTube, but beggars cant be choosers) that people recommend that encompass the whole process, instead of just pieces? Id like to understand it instead of just fumble through it.

To further simplify.

For step 1+2 , the router might have a built in DNS resolver which would eliminate the need to maintain another container or service.

For step 5, depending in the router software, with a single target (e.g. a nas running docker services) you might also be able to add a wildcard rule to catch any query for *.local.domain.com to resolve to that machine. This would simplify adding things in the future as the only thing remaining would be the caddy config.
