Base game, no. The Adrenaline Pack Pt 1 DLC has rallycross tracks, a few dirt circuits, and a few classes of cars for these.

Remote Wayland, no, as it isn't network transparent like X11 is. You can still do remote desktops, though, usually with RDP or VNC. On the popular modern toolkits, this works out about the same, since drawing applications through X11 is not so common anymore.
Personally, the main thing keeping me on Xorg is support for global keybinds. Plasma and GNOME both have support for the XDG portal which mostly addresses this, but apps still needs to adopt it. Plasma also has a workaround for global keybindings, but I don't use that. Sway doesn't have any good solutions for this last time I checked.
Overall, I like Wayland more but I need support for global keybindings for at least a couple programs I regularly use.
That is a massive nerf, but I don't think it'll stop me from picking it.
Does the Mass Effect 3 multiplayer count, then? There are RPG elements, there are a bunch of playable women, and it is all about stomping hordes.
If this sounds appealing and you aren't already aware: this is not available in the remaster. Andromeda has a version of this, too.
Arma is an interesting example. I'd say that it is only an open world game in some scenarios, and often times is a linear game that happens to have a big map and sandbox.
In any case, I'd agree that it having a large world with many possibilities is important for the gameplay and ability to mod/create content across the maps.
I personally use Matrix for text and Mumble for voice, but most probably won't go anywhere. Discord is convenient, and most users won't care enough about some extra ads to put in the effort to migrate.
In case it is helpful: Big Picture Mode does show non-Steam games. Go to the library and there is a tab for them. They'll also show in the recent games list on the home page.
I feel like this is an improvement over previous iterations. Gaming time is often stigmatized, and this makes it easier for some to share their Steam Replay with friends.
I played this all day yesterday with a bunch of friends. Safe to say that I'm enjoying the update!
Recent conversations with friends had me playing Star Fox 64 earlier last week, which has been very nostalgic.
Over the weekend, I was surprised to have a couple friends who I thought would never want to play an Arma title show interest in playing Arma Reforger with a group of friends I play with. I got to play a bunch with one of those newly-interested friends yesterday, and was super pleased that she enjoyed it.
The Steam Deck compatibility notes for the game specifically say that it isn't good at handling multiple controllers:
I think it is likely that this problem comes from the game, not a problem with streaming sending the inputs. You can try testing this in another game with more flexible controller support to narrow it down.
