Looking for advice on how to share pdf files with iPad from Mac.   Pages seems to only recognize text.   What app is recommended for pdf documents?

Welcome to Apple Support Communities!
If I understand your question, you want to read pdfs on your iPad, not create or edit.
Drag pdf files to the iPad icon in Finder while connected to your computer via the USB cable.
They will show up in the iBooks application
(If you don't already have iBooks, it's a free download from the App Store.)
Once installed, there are two buttons at the top left of the Bookshelf.
One is Books, the other is Collections.
Tap Collections, and you'll see Books and PDFs.
Tap PDFs and you're there.
