I had a toy when I was a kid that took 6 AA batteries. Now I know that means it wanted around a 9V input. But why did it take 6AAs instead of one 9V? The 9V would’ve been smaller and lighter, wouldn’t that have let them make a smaller battery compartment and save on manufacturing costs?

This is the same sort of question as asking why a boombox needs five D cells, and not just five little button coin cells. Both are 1.5v per cell, so what’s the difference?
The difference is ability to supply current, and capacity.
The bigger the batteries, the more power they can deal out, put simply.
9V batteries kinda suck for that. They’re just used in applications where 9V is necessary for the electronics, but those electronics don’t actually use much power.
