You do not have to pick between ZenRows and BeautifulSoup - they compose nicely. Let ZenRows do the heavy lifting: js_render true plus js_instructions for interactions (click, wait, fill, wait_for) executes everything on their side, and the returned HTML is the fully rendered DOM, which you hand straight to BeautifulSoup. Best of both: ZenRows handles the anti-bot and JS execution, BeautifulSoup handles the parsing with the selectors you already know.

Context: Stack Overflow (Adding BeautifulSoup to ZenRows, accepted answer): ZenRows returns the rendered HTML which you can feed straight into BeautifulSoup - response.html then BeautifulSoup parsing works on the full JS-rendered DOM. The useful part is combining it with ZenRows' js_instructions param (click, wait, fill, wait_for) so interactions happen server-side before extraction, then parse the result locally with BeautifulSoup selectors instead of ZenRows' own extraction.
