I did some searching, and apparently he’s a Five-spotted Hawkmoth, aka my garden nemesis, the tomato hornworm! Never knew those hornworms grew into these adorable giant moths.

They’re super cool. We relocate a good number of them to the volunteer tomatoes in other garden areas when we remove them from our intentional ones.
