But now you changed condition and you're rendering with hdri, this isn't solving anything
Then what is the main issue?
Wasn't the problem that you can't make nice orange juice?
Yes, I cannot make it cause light can't directly pass through it.
The settings you posted last don't change that. You cannot shuffle scene, camera and lights around to make it look almost like what it's supposed to and call that a solution.
here are your settings in the original scene
Your settings make weaker absorbtion and shifts colors in the volume, and using bidir+metro does nothing but slow rendering down
Now I remember, when I tried to make human skin material I found that light doesn't pass through. If light goes through ear for example, it should be illuminating cheek, but it doesn't unless you make skin material a bit translucent.

I didn't do that, just took two of my high quality, proven hdris, and put some nice material on the plane, and that's it.
(Oh, and I used a little DoF.)

Here are comparisions illuminated by only Sun and sky.
BiDir, Metro
Path, Sobol + LightTrace
You can see difference in the shadow too, so the light does pass through it (at least with BiDir), even if it is a dense volume, so it's not so obvious.
I tested few hdris too and it's probably easier for the renderer to find lightsource than sun and sky..
But that's not changing anything about the issue itself

So you changed everything but the glass in other words
Your scene how has different and much simpler lightsource and dark ground...
But like I said, even if hdri makes it somewhat easier for metropolis to render things, it doesn't solve the issue at all
