PDFs are a convenient way to preserve formatting and accessibility information, assuming the file is converted and accessibility is reviewed correctly from Word. Many users may access PDFs through Adobe Acrobat, though, not all PDFs are created in Acrobat.
Things to remember when converting Word to PDF:
Sighted users can make associations between headings, rows, columns, and other data. However, these entries are difficult if not impossible for accessibility users. Adobe Acrobat has a number of functions to identify the reading order of these entries under Accessibility in Tools.
Adobe also has an extensive tutorial for how to list the reading order: https://helpx.adobe.com/acrobat/using/touch-reading-order-tool-pdfs.html
