Same here. My old Pi 4, was running HA, Nextcloud, Ghost blog, websites, Jellyfin and a couple of other small things. It did it fine, but when I upgraded to the Odroid H3 it all became so much faster and snappier.

So what you are really asking is what platform developers provide the best applications (video editors edition)?
My biased answer here is KDE. But I haven't used video editors in years, so it's also an outdated opinion.
That is quite an extensive network you got there at home.
Lots of servers, VM's and docker containers working together.
Mine is just 1 small server with a bunch of docker containers running.
You are way more involved than I am. I usually just do pacman -Syu
and yay -Syua
every couple of days and then pacman -Sc
about once a month to clean out the package cache.
Sure, play your youtube videos on Lynx.
We all know that's one of the main things people use browsers for, that's not work, these days. ;)
Also, I'll just mention that it all means nothing as soon as you open a browser window. Then all your RAM is gonna be used up anyway.
Maybe OMV installs it by default?
