I believe the answer is yes to all the examples you gave. The only part you left out was grease pencil’s ability to draw directly onto the surface of 3D objects. Paul mentioned in another post that grease pencil also has baking capabilities which I’ve added to my list of things to look up. As an illustration software, Blender can do that. Just note that it doesn’t follow your traditional illustration software workflow. Plus it’s designed to be a 2D animation system that works with the 3D animation system.
