Sound can vibrate through many media and does not need air to work in
water. Then why would they have thought that light required aether in
the MMX when it had the air for a medium?

When light is regarded as a wave then the electromagnetic field is
its medium.
Anyway, there are experiments that show that light does not behave
like a wave in any medium would.
Much of what is known about light was not known at the time of the
original MMX. But any explanation of MMX with light as a wave in
air is refuted by the Fizeau experiment, which Michelson and
Morley performed with a better accuracy that Fizeau had done.

The Fizeau experiment is parsimoniously explained if we regard the water
as the medium of light.
The same for the MMX considering that the permittivity and permeability
of air is very similar to a vacuum.

Yes.

as the medium of light.
No, in particular the part where the moving matter was air.
But even co-moving water increased and counter-moving water reduced
the speed clearly less than by the speed of water.
The same for the MMX considering that the permittivity and permeability
of air is very similar to a vacuum.
What is "the same"? That both water and air are good otical vacua?
Or that neither of them is?

The fact that the speed of light changes in the direction of the flow of water shows that water is the primary determinant and is the medium.
The question was, why did they think in the 19th century that the air
wasn't the medium in the MMX?
You beg the question of the medium since the electromagnetic field
requires one itself. The air provides one.
The fact that the medium determines the speed indicates that air is the medium in the MMX.
What is the same is that air and water are sufficient media for light.
