Yeah porkbun is good.
To see how the glue records work, you can run dig +trace example.com
This answer goes into detail how it works behind the scenes.

RFC 2606 is your friend ;-)
I use porkbun.com for my domains, which is excellent, and also has glue record support.
https://kb.porkbun.com/article/112-how-to-host-your-own-nameservers-with-glue-records
The thing you want is “glue records” the upper level server would serve ns1.example.com (this is an approved domain for example use, better to use example.com than making your own example up) as the authoritative name server. Then provide the glue record which says “ns1.example.com is at IP address X”.
It should ask for IP addresses as well as hostname. Otherwise they only assumed people will “host” their domain in another hosted, as opposed to self-hosting.
In that case (and in any other case) change your registrar to someone else who supports glue records.

Lots of people contributed really good answers, so I don’t have anything valuable to add to their answers. But I wanted to point out for your detailed question, you include what you have done, what is your understanding and what are your shortcomings clearly. As opposed to a lot of posts with vague, detail-challenged narratives, that’s a top notch post.
And the community delivered by giving good answers, so go community!
Also, you didn’t just ghost after the initial post and interacted.with the people who graciously donated their time, so another bonus point there, as well.
I have been using porkbun.com as a domain registrar.
For email hosting, self-hosting is a lot of effort. If you just want the damned thing to work. I’ve heard good things about Fastmail, and personally I’m using migadu.com. it’s $19/year for micro.
Use any imap client, or if you want to keep using what you’re using Gmail and Outlook and Apple mail apps w all support your new personal account over imap as well
Lots of relevant comments in this post https://aussie.zone/post/4286731
Same here.

in addition to “dedicated Nas + compute node” and “just use a desktop” suggestions, there’s the microserver option in between. Small, but has enough power to run stuff other than storage.
Hp proliant microserver is what I use, you can try getting a previous generation from second hand market.
i also think that it’s overkill, especially for a minimalistic tool like wireguard. That’s why I mentioned “if you want to be extra paranoid”. This forum is for learning, and this question is an open ended learning question, hence, an opportunity to learn about port knocking, even if the actual real life benefit of that would be minuscule.
Good point, kernel updates should be paired with reboots to get kernel patches applied quickly.
Yes wireguard would only accept connections clfrom clients with known certificates, but this is “belt and suspenders” approach. What happens if there’s a bug in wireguards packet parsing or certificate processing? Using port knocking would protect against this —very remote— possibility.
VPN software usually is built strong to begin with, and any vulnerabilities discovered will be promptly fixed as well, so updating frequently should suffice. (Why not automate it with unattended-upgrades
package?
Using a random high port number will probably hide it well enough for Internet-wide port scanners as well.
if you want to be extra paranoid, you can hide the VPN service behind a port knocker as well.
I recommend https://migadu.com. not free, but the lowest price tier has lots of features, unlimited mailboxes etc.
See https://lemm.ee/post/4593760 for a related post and more discussions about pros and cons of each.
You would need to create a new torrent whenever new files are added or edited. Not very practical for continuous use.
