Set page for PDF to open to In Adobe Acrobat (2019) you can set the page that appears when you open the PDF in the File > Properties > Initial View (tab). Preview always opens the document to page 1. Adobe Acrobat Mac/Win will open the document on the specified page. Does Preview support this functionality?
No. Preview does not respect the PDF Initial View metadata. Other Readers, such as Skim and PDFPen Pro, also do not. Instead, all of these apps open at page 1 and then remember the last page viewed for the next time the document is opened. Foxit Reader does respect the Initial View.

Your best solution is to provide a Table of Contents (aka Bookmarks, Outlines), so that users can easily click to the desired page.

It's worth noting that Preview's own 'Bookmarks' are not PDF-standard, and will not be displayed by any other PDF Viewer.
