Navidrome with Substreamer on mobile for auto-generated recommendations based on already played music works great for me.

Calibre Web has Kobo integration, although I’ll admit I haven’t been able to make it work so far: https://github.com/janeczku/calibre-web/wiki/Kobo-Integration

Jitsi also provides integration with Matrix chat.

Heroic for Epic, Lutris for GoG, this approach worked best for me so far, I ran into issues when trying to run both stores in one application.

For a less obvious use case, I did some light video editing with Kdenlive and an external monitor, mostly because the Steam Deck is more powerful than my laptop ;)

Also PS2 emulation, Burnout Revenge has not aged one bit and plays very conveniently on a handheld.
