I don't really like testing for $files not empty as my logic condition. It seems a bit "indirect". But, I couldn't come up with a better approach for knowing whether there was pipeline input or not. Is there a better way to handle this?

You don't need to use $_.
If called from the pipeline, $Path will contain one item at a time. If fed directly on the parameter, it'll contain a collection. So, either way, inside your PROCESS block you use a ForEach to enumerate $Path. It will ALWAYS contain SOMETHING because you've marked it as mandatory. Check out my Toolmaking book if you like – there are a slew of examples of doing this. The code's on MoreLunches.com.
