Where I work we prefer jQuery to the native DOM API for scraping. It really speeds up the process of extracting data. For example with Puppeteer you can do page.injectFile("jquery-3.2.1.min.js"). I think that would simplify your evaluate() calls. It would also be easy to speed up the whole process by doing a single evaluate() call per page with all your scraping code in it.
