Could it be that your model has black vertex colors? Can you in the PBRGraph material in Unity check “show vertex colors” - does it also appear black in Unity if you do that?
It shows green whether i enable or disable vertex color

that sounds like you still had the asset label on the first material
Depends on your target devices. Generally ~200k vertices should be fine. Rendering shadows effectively renders everything twice, so keep that in mind for scene complexity and if you really need them and so on, especially when targeting low-end mobiles or mobile VR headsets.
