I would guess steam deck 2 will be x86, I'm assuming that valve is already working on hardware for it. We do know that Valve is working on a new VR headset that will be ARM based though, and that they're working on an ARM compatibility layer for it. If the early testing of the VR headset is promising enough I could imagine valve pivoting to make the next Deck ARM based, but that will probably cause a longer delay before we get a Deck 2.
Unfortunately common issue with a lot of Epic store games, many don't work or have issues when compared to the steam version. The protonDB reports are all 6months+ in age as well, so it's possible something has changed with the game in that time. Found this discussion on reddit, where it sounds like it runs for most people but with terrible performance.
I know some Epic games take a really long time at first load. The Epic version of gloomhaven could take 1-2 hours to load the first time if I recall right, but after that first really long load time it would work fine. I'm assuming it's compiling shaders or something the first time.
For trackball, I personally find a finger controlled trackball much more intuitive and easy to use compared to a thumb controlled one. The trackpads on the deck and steam controller are great, but they generally are thumb only unless you have some really funky grip.
You can use any mouse. Also after an initial learning curve, trackball mice are a very couch friendly mouse.
It's cool that the switch 2 has a mouse mode, but it's not very ergonomic and it's pretty limited in terms of comfortable inputs.
Ars Technica is generally excellent in my experience, one of the better tech news websites.
It's distributed through flatpak, so yes, it's available on Ubuntu or any linux distro that supports flatpak.
It is focused on controller support, so it might not be ideal for an ubuntu desktop computer, but that just depends on your use case.
According to the article this has a built in adblocker.
I think it was supported really early on (or was supposed to be supported), but it hasn't worked for basically the entire time I've had my Deck. I don't play with keyboard very often so it never impacted me, but I know I've heard people complain about it.
From looking it up, it's usually a BA, but it can be a BS depending on focus.
SimplyDeckyTDP has a few features that specifically care about the sleep and resume features. You can disable setting the TDP when resuming, as well as disable any suspend actions. For me, the most useful setting is configuring the max TDP when resuming from sleep. You can encounter audio stutters when resuming games sometimes, and forcing the maximum TDP when waking the Steam Deck gets around those issues.
That's interesting, I don't run into that issue often, but I know some games have issues with it. The pause games decky plugin already can fix some of those, but worth remembering this plugin as well for when people have trouble with that.
I've had Sekiro on my wishlist for a long time because a lot of people consider it the best souls like game. I know the main point with it is that it's supposed to be more parry focused, you're expected to really learn and master enemy attack patterns and parry/counter windows. The first playthrough is supposed to be able slow/steady progress and learning, and then on a second playthrough you apparently feel like a god who's mastered an intricate dance and can't be stopped.
At least that's how it was described to me, but as far as the smaller "what do I do now" level I don't know what to tell you with my general lack of souls experience.
There were previous leaks that were covered here about it, here are two articles on it:

https://www.gamingonlinux.com/2021/09/deckard-is-apparently-the-codename-for-a-possible-standalone-valve-vr-headset/
As with anything like this, it's not 100%, but it's pretty much confirmed that valve is working on getting x86 vr games to run for ARM hardware, which is enough for most people to assume that an ARM VR headset is coming.
