Please list for me the alternatives that are so ubiquitous as PDF that I can send someone a copy of a document that they cannot modify while still being able to read/print/etc, and is not a pure image format that is multiple MBs in size.
Except Acrobat lets you modify PDFs. If you're trying to send someone something that they cannot usefully modify, you're kind of doomed from the start.

Acrobat won't let the Average Joe modify a password-protected PDF. Neither will Preview. There are ways around it, but for 95% of the people receiving a PDF, it's as good as locked.
That's why these "read-only" PDF are laughable. Just sign your PDFs (there is full support, no excuses possible) to create an authoritative/accurate version.
