I use Xournal - https://sourceforge.net/projects/xournal/

It lets me type in to forms - or draw text over them if necessary. Then I paste in a scan of my signature. Then save as a PDF an email across.

I've been doing this for years. Job applications, mortgages, medical questionnaires. No one has every queried it.

If you're hand delivering a printed PDF, it's just going to be copy-typed by a human into a computer. No need to make it too fancy.

I used Xournal for a couple years in college. It was perfect in how simple it was to mix handwritten and typed notes or markup documents. The only thing is that I wish it had some sort of notebook organization feature. It would have been nice keeping all of my course notes in one file, broken down by chapter or daily pages. Instead, I ended up with a bunch of individual xojs that did the job but made searching for material take longer.

macOS's preview will let you do all of this also.
