I'll be the "swing vote" LOL
I have done all of the above at one time or another. :-)
These days it really depends on the meat, I almost always rinse chicken, just because they usually have a ton of juice in the package and yardbird juice is slimy. Everything else its just depends on how much juice is in the pack, pork I rinse about 50/50, rarely do I rinse beef.
Not your exact question but most included in their answers, lately I haven't been using any binders (oil/mustard/etc), Meathead talks a bit about binders in is Rub article
https://amazingribs.com/tested-recipes/spice-rubs-and-pastes/science-rubs (real interesting info on mustard as a binder), and I am not sure if it was him, Alton Brown, or just a lucid dream, but I saw something recently that talked about oil actually forming a barrier between your meat and rub and not letting your rub penetrate as well into the meat, it got all "sciency" which is the way to this "software engineer's heart" so it made sense to me.
To apply my rubs these days, I just apply to the meat, then wait 5-10 minutes for it to develop a wet look, before turning and applying to the other side. If the meat is fairly "dry", I will use my spritzer and just dampen it with water/apple/pineapple juice.
