I get that everyone stores/carries fat differently but wouldn’t it be more efficient to have a system where the fat near whatever muscles doing work gets broken down first?

Some fat actually is stored in skeletal muscle fibers, along with ATP, the body’s main source of fuel. Fat is not directly converted into energy. Fat is broken down into different lipids, which are carried by the blood and then converted to ATP, just like sugars, meaning carbohydrates, are. The body breaks the ATP down into carbon dioxide, water, heat, and ADP in the mitochondria. There’s really no benefit to having non-skeletal fat stored as close to the muscle as possible, as any deficit of fat derived ATP is not due to the delay in transport.
