All of that stuff will just be what I mentioned before - opaque surfaces will mark higher resolution pages and sometimes those pages will also overlap the places it needs shadow data for the translucent surfaces. As you zoom out the pages become bigger and this becomes more likely to some extent, but you can still set up views where it will not be the case. How much of a problem it is depends entirely on the scene.
The translucent quality mode is the only way to guarantee you get high res data and filtering, and even with that on, only for the first layer of translucency (as with Lumen first layer).
