FAT is finicky but FAT is not the issue here. As long as the machine has sufficient time to complete its last writes and you don't have any programs running using the disk, it should always be safe to shut down - DOS doesn't buffer or delay writes unless you have some sort of disk caching program running and if your disk cache is doing something fancy it will have its own shutdown procedure.
Hard drives also have write caches and often run with write caching enabled. The solution is the same - wait a few seconds for the last writes to be flushed to the media. And the same will apply to any other storage device, USB sticks included. Make sure the system is quiet for a few seconds so the device can commit it's writes. Then shut down.
