Any clinical experience will do.
Scribing in the ED would be an excellent avenue for broadening one's exposure to medicine. And it could be exciting, but also consider the stress-prone, very-rapid pace of the work, which must be performed within exacting parameters during weird shift hours. A lot of scribes don't make it past the probation period for good reason. I don't think interviews would often touch on the factors you listed above, but they're good to know for your own sake.
Optometric techs get to see interesting cases, too, but heavily leavened by routine screenings. If you thirst for more excitement, some ED volunteering on the side could provide it.
