So far the only games I've ever played on Deck that require them would be Portal 2 alongside the Portal 2 mod Revolution (or something along those lines). I think jump and maybe 1 other function is tied to the back buttons. Otherwise, I haven't messed around with controls enough to find a use for them.

Fast forward in emulators. Also, the menu toggle in Retro Arch.
In Dungeons of Dredmor, an old mouse and KB roguelike, the community made a good layout where every button is mapped to a keyboard key to open the various inventory and crafting windows, etc. With the track pad right there to act as a mouse, it's honestly just as good as a mouse and KB. Maybe even better.
In games where I've have to hold a face button, yet use another I'll use the back buttons.
So I mirror ABXY in Hades II for example, and charge up my B spell while I dash away with A. Much more comfortable to charge with the back B and dash with the face A button.
