Anyone able to ID these Beetles or Stink Bugs that found some Columbines? [Salt Lake City, Utah]

Discovered some shield-like bugs that took residence over my wife's columbines last night. After some regular searching, I think they might be some kind of variety of stink bug, but they're quite a bit smaller than the regular stink bugs that we tend to find around here (such as the Brown Marmorated Stink Bug). They're approximately the same size as a regular lady beetle, ~8mm-ish in length. I guessed they might be Harlequin Bugs, but their eggs are not even close to being similar.

They do not appear like they have done any damage to the plant, fwiw, but it might also be somewhat early in their occupation.

Anyone have any better guesses? https://imgur.com/a/tQ8iKlF
