I think for the purpose of 99% if the self hosters, which is an instance for maybe a of a couple of hundred of users, this doesnt matter at all:
If that's what you are using it for, I would suggest looking into Matrix / Element. Just as easy, completely open source and self hostable. Wide variety of client choices for every OS.
I am not a fan of telegram, but the clients and the protocol are open source.
Never heard of it, sounds good. Unfortunately it doesn't work for me, since I am not interested in "Creators" but Content. But I guess a lot of people are curating their media by personality and not content subject.
So, the government job does not pay well enough so you can pay for Netflix & Disney+ or why do you want to host our own movie streaming?
In any case, check if the camera apps can take raw images, that's the first step to better pictures on older phones. I like ProShot but I don't know if it's working on your phone.
For future purposes:
I didn't understand if you want a desktop GUI or a webUI, there are a lot of projects dealing with ai upscaling, I don't know which of those you can get to run on the RPI.

To watch stuff without ads and tracking, but still streaming, you can use clipious or newpipe on Android and android tv. If you want to replace the entire YouTube GUI with an ad free selfhosted one, check out
Boy, can "guerilla" marketing get more obvious?
Nextcloud works great for document management, if you additionally install tesseract OCR and Elasticsearch. Then you can use any smartphone document-scanner (I personally use "swift scan") to add new documents via WebDAV Upload, but I think most of them support WebDAV nowadays. The Nextcloud app even has a document scanner feature built in, but it's not very good.
I have been reading about the features of paperless-ng and I don't see what that software additionally brings to the table that a properly setup nextcloud cannot do. Only that I have Nextcloud anyways and it can do much more than document management and I love to have all aspects of my "personal cloud" in one software tool.
I don't know how much configurable invidious is in terms of allow-listing content, but unless you want to locally cache the content you want them to see - which seems a lot of work, I guess that's the way to go
I am collecting hard to find art house stuff. So I have redundancy, but no backup. If your collection is easy to redownload I totally would use the interwebs as my backup.
I think a lot of proxy servers have that functionality, HAproxy definitely has... With nginx you need the "plus" Version to proxy tcp.
security
i think you are completely wrong here. big corporations do cost assessments of security vs costs of security breaches. if security is more expensive than data breach, they will accept the breach.
Unpopular opinion: don't use any of the Truenas, unRAID, freenas, Openmediavault, proxmox stuff. Sooner or later you will run into something those special interest systems can't do and it will feel annoyingly limiting.
Choose a widely used vanilla Linux distro, Debian or Ubuntu, install everything as docker container, learn how to handle docker compose and how to configure stacks via docker-compose.yml
I think the most advanced OpenSource LLM model right now is considered to be Mistral 7B Open Orca. You can serve it via the Oobabooga GUI (which let's you try other LLM models as well). If you don't have a GPU for interference, this will be nothing like the ChatGPT experience though but much slower.

You can also try these models on your desktop using GPT4all, which doesn't support GPU ATM.
