New pending application generates staff notification

I removed the image as one could still see PII from the pixelated section.

There is a site setting for that, see default trust level site setting. I/We strongly suggest leaving this at TL0 though.

You can be either of the 2 or both, there really isn’t subsets here. Even though there were, admins cannot be a subset of moderators as they have more abilities than moderators. See Description of various user states in Discourse (Admin / Moderator / Staff / Developer / Other) for an explanation of each one.
