Can a node detect when a node is deleted via queue_free() in a similar way to how an area2D can detect bodies exiting it, and can this be used in code?

Yes, see tree_exiting and tree_exited here - https://docs.godotengine.org/en/stable/classes/class_node.html#signals

However, depending on your code structure, it may be best to just have the node that's being removed use a custom function like the following:

func terminate():

Although this code will emit the signal before the node is actually freed, so if you require a signal to specifically be emitted afterwards, then tree_exited is probably your best bet.
