Last Chance to Fix EIDAS (Mozilla)
> 1. Is this proactively monitored for? And how? And by whom?
Yes, security researchers and domain owners use Certificate Transparency Monitors to search for certificates. e.g.:
https://crt.sh/ - allows you to search for certificates for a domain
https://github.com/SSLMate/certspotter/ - open source tool which notifies you when a certificate is issued for one of your domains
https://sslmate.com/certspotter/ - commercial service that does the same, operated by my company
> 2. If a major state-level CA was discovered to have issued a mitm cert, would browser vendors really take the commercial hit of removing or distrusting their root cert?
In 2017, Chrome and Firefox distrusted Symantec, which was at the time the world's largest certificate authority: https://security.googleblog.com/2017/09/chromes-plan-to-dist...
Symantec hadn't even issued MitM certs - they were just grossly incompetent. Distrusting them was very painful, but necessary to upload the integrity of the CA system, and demonstrated conclusively that there is no such thing as a too-big-to-fail CA.

Encrypted traffic interception on Hetzner and Linode targeting Jabber service
Indeed, a CT monitor which sends alerts about legitimate certificates is pretty much useless due to noise. My service, Cert Spotter, provides an API endpoint[1] which you can upload your CSRs to, so you don't get alerted about certificates using the same key as the CSR. The open source version of Cert Spotter can invoke a script[2] when a certificate is discovered, and the script can cross reference against a list of legitimate certs.

You shouldn't run NSA-grade Wi-Fi at home
You can roll your own with https://github.com/smallstep/certificates. We maintain major open source projects and contribute a lot to other projects. I don’t think that means everything we do has to be open source. Sorry this one wasn’t. Doing this in pure open source would be a book, not a blog post.
Love Let’s Encrypt — we’re sponsors — but using them for WiFi is a terrible idea. You need internal PKI for WiFi.

Distributing ACME Let'sEncrypt certs for homelab
letsencrypt was always about moving the public internet off of http, it doesn't really make sense to use it throughout your internal network. but if you really want TLS and ACME for auto renewal, other solutions are available: https://github.com/smallstep/certificates

SSH With SSO
You could try step-ca: https://github.com/smallstep/certificates. There’s an OIDC provisioner for SSO and you can sign (short-lived) SSH certificates with it.

Web application to manage self-signed certificate authorities/certificates/keys
You could also check out out Step CA: https://github.com/smallstep/certificates and the accompanying CLI. It has an ACME server and other methods for requesting certificates. It can work/integrate with your existing root(s), too.

ACME setup. Domain required?
This is a lot more complicated setup but it works for me. I run a private CA called step-ca from smallstep and it provides CA and ACME endpoint. I use a .home domain. The trick is the validation for non-http devices which is typically the DNS-01 challenge. For this, I have unbound in pfsense setup to work with acme-dns so I can keep everything internal. Again its complicated but if your learning cyber security it might help get a handle on all things TLS. Btw way behind the scenes I think the ACME plugin is really just running acme.sh bash script which is really good. Final reminder as other have stated. Private CA is great but you need to distro the roots and intermediates out to your clients for trust. If all your trying to do is have an https web gui for pfsense from one device its pretty easy.

Using k8s-apiserver as AAA server for microservices?
I was just looking at https://smallstep.com/certificates a few days ago. It looks like they have an operator that fits your description as well as example docs for setting up inter-microservice mtls.
