Sorry for the late reply. I don’t check Lemmy all that often.

I would never want to use a clip on case myself. I would worry that it would make the buttons uncomfortable to use. It would also affect how it sits in a docking station. The Steam Deck has a nice shape that will make it harder to drop. I wouldn’t recommend a case, but some people do like cases, so that’s your call.

USB hub sounds good, and would also work better than a dock if you do get a case.

The ABXY buttons are very comfortable to use! I’ve found the Deck to be a very comfortable device. My hands are a bit bigger so I’m not sure how big of a role that hand size plays, but I think you’ll be fine.
