I have listed your options for direct page access in Pages v6.3.1. There is another approach. Either open your Pages document directly in Preview, or export to PDF, and then open that PDF in Preview. From the View menu, choose Contact Sheet, and by default, you will get four-up legible documents with page numbers per Preview page. Keep this open, concurrent with your Pages document.
In addition to the Office 365 subscription plan, Microsoft does offer a single purchase of Office 2016 for Mac. Word has been in continuous development for 35 years, while Pages v5/v6 since 2013. Because Pages is a free application, and engineers cost real money, do not expect significant feature updates where no revenue stream can justify the expense.
I no longer rush to recommend the free LibreOffice, which is an MS Office superset, and under one name or another, has been in continuous development since 1992. It does have very good Word document compatibility, better than Pages, but it will cost you significantly in learning curve, with little to no support, and documentation that is now an entire version out of date.
