oh it is still being updated! great.

I'm aware of FreeTube and PlasmaTube, which IIRC both require an Invidious instance. There was something called SMTube in the past, not sure if it still exists.
Nothing I'm aware of has both desktop and mobile version, but if anything there are more options for mobile YouTube clients; try NewPipe or Clipious.
Edit: SMTube does still exist. It does not require Invidious, but it does use tonvid.com.
Revolt is the most Discord-like FOSS chat app; it's very easy to use and customizable. Rocket.chat and Mattermost do similar things and are more oriented toward organizations (the Slack/Teams Classic use case).
What makes this extra confusing to me, is that this doesn't seem to happen to the same extent for Invidious instances. I've only needed to swap between two instances on Clipious, whereas on LibreTube I was hopping across their entire instance list and sometimes not finding even one working instance.
I listen to music all the time, so probably, but most of the true sensory overloads I remember were when the album I was playing already finished and I still had them on... so I suppose I'll keep that in mind, that transitioning out of noise cancelling may be easier during music.
I suspect a lot of "evil admirals" were promoted by votes from, or just to appease, reactionary political movements.

Memes go in !risa, fan theories go in !DaystromInstitute, and Star Trek related off-topic discussion go in !Quarks, otherwise, I don't see why not.
The problem is, for me, noise cancelling often either isn't enough, or creates a much bigger sensory problem when I inevitably have to take the headphones off.
And the settings with a big enough loudness problem to justify noise-cancelling tend to be ones where having to turn it off is inevitable before the noise dies down (to talk to someone)... so I usually don't bother.
Most regular distros are good enough for gaming. The only issue you're likely to run into is with graphics drivers (I recommend going for AMD graphics on that build), and the availability of certain software in certain formats (gaming software is more likely to be available for Debian or Ubuntu based distros).
If you like the Steam Deck's desktop mode, you might enjoy another distro with the same desktop environment (KDE Plasma). I'm partial to KDE Neon, a snappy Ubuntu LTS spin with all of the latest KDE software.
