cartilage
No. Flat bones consist of spongy bone sandwiched between compact bone.
spongy and compact
Spongy bone is not filled with cartilage. Spongy bone is composed of trabeculae, which are interconnected plates and rods. Cartilage is a different type of connective tissue that can be found in joints and in the growth plates of bones.
Spongy bones contain what is called cancellous tissue, which is bone with a spongy or honeycomb appearance. This is where new blood cells are made.This cancellous bone framework is called the erythropoietic framework because it makes new blood cells.

The compact bone surrounds the spongy bone and provides structure for the body.

The bone is constructed of compact and spongy bone, unless you are referring to the cushioning between bone that bend called joints, you would have to be more specific
Spongy bone, also known as cancellous or trabecular bone, is a type of bone tissue that has a lattice-like structure with bony bars and plates separated by irregular spaces. It is found at the ends of long bones and within flat bones, providing structural support while remaining lightweight.
The thin bony columns in spongy bones are called trabeculae. They provide structural support and help distribute forces within the bone. Trabeculae also contain bone marrow, where blood cells are produced.
