Why did Young specifically perform a double-slit experiment to demonstrate the wave nature of light
Have you seen Young's original description to the Royal Society in 1803? He did not do a "double slit" experiment as we would describe it today. The first experiment that he describes, uses a single obstacle of width 1/30 inch, which is basically the complement of a single slit.
