With BBox present there is no need to simplify.

Looks good. I would add a tiny explanation for those like me who don't have much of a clue about what's going on here as to why we don't need to use the second query if the pixel ratio is within the limit or if we have a bbox 😬

also (but this is veeery much my preference for ternary operator), this could be written (more concisely in my opinion) as

const query = (ratioPixelExtent < 8 && !filters?.bbox) ?
  `( SELECT row_number() over() as id, st_centroid((${gridShape}(${gridSize}, \
        ST_Transform(ST_TileEnvelope(${z}, ${x}, ${y}), 3857))).geom ) as the_geom )` :
  `( SELECT row_number() over() as id, (${gridShape}(${gridSize}, \
                    ST_Transform(ST_TileEnvelope(${z}, ${x}, ${y}), 3857))).geom as the_geom)`;
