... sometimes they need to make minor edits to legal lines and such. As well they require both for archiving purposes. I've seen third party aps that let you edit pdfs. I think I will experiment with converting the text to outlines.

Oh gosh no. Don't do that!
If you want the PDF to be editable, then do not convert the fonts to outlines; that creates graphics of each letter and the text can't be edited!
Leave the fonts/text as is, and when making the PDF, embed the fonts into the PDF. To export a high-res PDF for printing:
File / Export / PDF (Print)
At the Export Adobe PDF dialogue, select either Press-Quality or PDF/X-4:2008 from the top-most drop-down.
Make any adjustments to the export settings specified by the print shop, such as to pick up the document's bleed settings. But generally leave the graphics and color settings as is. This setting also automatically embeds the fonts into the PDF.
RE: Fonts, you can use any brand of OpenType/Unicode fonts in your InDesign layouts, not just those available through Adobe.
Google Fonts are professional quality fonts that are open-source: that is, you can download them to your computer and install them, use them in any program (not just Creative Cloud apps), embed them into PDFs, and package them for your print shop. "Open-source" means that they have a very generous and liberal user license. See https://fonts.google.com/. And Google Fonts are free and don't have any additional licensing fees.
Other font foundries, such as Linotype https://www.linotype.com, Monotype https://www.myfonts.com, Fonts.com https://www.fonts.com, and many others, also have OpenType/Unicode fonts you can purchase (not free). But they do have additional fees for embedding the fonts into PDFs, usually on a per-document basis.
