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.
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?
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:
