The space ship flying clip is from Whisker Squadron: Survivor and the other one is Ratchet & Clank: Rift Apart (it’s an awesome game, give it a try).
Someone made a list of all the games from the trailer too if you’re interested. u/mulard from reddit gets all the credit for this list.
had the same question so started compiling something, hope this helps.

Edit: I filled out the rest using some Google Lens searching. Let me know if any of them are incorrect and I’ll update
Wow the formatting got ruined from the original comment, no bullet points on Lemmy I guess? Did my best to separate stuff but there’s still no space between the list number and title of the next game.
I believe Steam is just showing you games that can run natively on Linux. You have to run Windows games through wine/proton like the Deck does.
I don’t actually have an anything except the Deck running Linux so I can’t help beyond that. I may even be wrong but it’s at least a place to start searching.
