So, I was logged in as admin, trying to pick images for an ACF gallery attached to a User—a different user. Of course, I realized that I had the “Limit the media library choice” option set to “Uploaded to post.” I wanted to use images that this admin account had uploaded but I guess that setting trumps all that. Close this one out!
