Any language you’re comfortable with is good for that. Ruby, JS, and Go come to mind the first because they all have solid ActivityPub libraries which are going to save you some time on interconnection. Any programming language can do static html.

I really enjoy writing clojure lately. the only thing that annoys me is the whole "hosted" thing where you either get a bunch of good clojure-native libraries or all the JS's npm mess (other clojure hosts are very much non-existent).
Why would you need specifically "cloud" logging for that? Spinning up grafana and loki is rather trivial in the modern containerized world and that'd cover 90% of what you want from logs. Neither is a resource hog, too, it's so much better that e.g. the ELK stack for logs that you only look through occasionally.
It's more of a chat-to promotion than a useful list. “Use firewalls?” No shit!
FWIW Sourcegraph chrome extension adds a neat “open in Sourcegraph” to github pages and SG is just superior. Why would you use Github's mediocre search either way ¯\_(ツ)_/¯
Not an answer, but a clarification. You seem to be messing up two things. DoH is basically encrypted DNS, i.e. no one other than your DNS provider can see what domains you ask for. It's orthogonal to ad blocking; there are various service that provide one, or another, or both.
Hetzner machine in that article is bare metal. It’s much harder to extract the certificates from a running server without anyone noticing.
Fediverse generally runs on ActivityPub, which uses HTTP as a transport, so you’ll be good. The problem is that the clients don’t talk to fediverse, it's more of a server-to-sever protocol; you'd look into the specific server APIs. But you’re good there, too - all the big fediverse players use RESTful HTTP for their client-facing API.
