More ways to query the contents of the blend file.

I downloaded a very simple file with 2 low poly objects. The file is 4mb. I downloaded another file with a whole mobile game character, rigged, animated, packed textures, multiple environments, and other things. The file size is 4mb.

I would like a way to see the file size contribution of every data block.

I have a scene with not that many objects, most are low poly, 2 are high poly, 8 are medium poly with a subdiv modifier. The BVH updating step before the actual render starts takes MUCH longer than then actual render. Also the Mr Elephant (mouse in front of a fireplace) demo scene is like this.

I wish there was something that would tell me which objects or modifiers are causing the time taken in the BVH stuff.

I need a way to find all objects with a bevel modifier and all with a bevel modifier that is active in the viewport but inactive in the render.

I need a way to find all objects of type point light whose name does not contain the text "point".

I need a way to find all objects that have camera visibility unticked.

I need a way to find all lights with a negative strength value.

I need a way to find all objects that are in more than 1 collection.

I need a way to find all materials that contain an emission shader node.

I need a way to find all objects that have only 1 child and are themselves the child of another object.

Basically I need a utility that will read a .blend file and extract almost all the data possible and dump it into an sql database so I can easily run useful queries on the data with inner joins and outer joins and left and right joins and basically any question I might want to ask I could easily answer.

Which scene has the most polygons? Which collection has the most polygons? Which object has the most polygons?
