The antimagic cone explicitly says it affects the Beholder's own eye rays. But does it only prevent using eye rays in the cone, or does it neutralize effects already applied?
Antimagic Field, which Antimagic Cone is based on, says
"Any active spell or other magical effect on a creature or an object in the sphere is suppressed while the creature or object is in it."
So I'm guessing the effect is suspended, but would resume if the target leaves the cone.
Would it revert a creature petrified by the petrification ray (temporarily)?
Good question. I think if you are partially petrified, you don't have to make the save against total petrification while in the cone. But once you're petrified, it doesn't undo it. I think once a spell or magical ability ends, if it doesn't say the conditions imposed end with the spell, they don't. Similarly if you cast Wall of Stone for the duration, it creates a mundane stone wall. A Beholder can't punch a hole through it with its eye. The Beholder can't revert someone to their original form after a True Polymorph is completed.

Actually on the last one they can, True polymorph isn’t permanent after full duration concentration, the duration just changes to “until dispelled” and the concentration requirement ends.
I think I’d agree the restrained condition and saves would suppress in the AM cone, but technically the flesh to stone spell only becomes permanent after its duration expires, so the petrified creature would revert inside the AM field if the duration was still ongoing for that spell. The eye ray version doesn’t have a duration though, so it’s either permanent from the start or it’s always magic/always affected by the AM. I’m just not sure which is the intent
Would it revert a creature petrified by the petrification ray (temporarily)?
I think so. The ray's effect specifically says it ends if they succeed the save, but doesn't say it ends if they fail. This logically concludes that the petrification condition is an ongoing effect of the magical ray.

It does say what conditions end the petrification.
The question is whether the Antimagic Cone counts as "other magic" that can end the petrification. I don't think so. It's other anti-magic. I think the petrification is supposed to persist until magic with text applicable to the condition is used. For example Dispel Magic might work. This isn't a spell effect, so we have to house rule, but comparing it to Flesh to Stone is good, so maybe a 6th level Dispel Magic or DC 16 spellcasting check works. Of course Wish could do it.
I'm pretty sure back in 3.5 the petrification ray actually did apply Flesh to Stone, so it might be reasonable to use that as precedent. Flesh to Stone is duration 1 minute, after which the creature is "turned to stone until the effect is removed". That would mean an AMF could stop you from petrifying, but not rescue you from being stone - once the duration is over, there's nothing for an AMF to end.
If you wanted to get a bit more narratively involved, though, petrified doesn't knock you unconscious - you're imprisoned in a sensory deprivation chamber made of your own body, unable to sense anything, much like the protagonist in Dr. Stone. It would be reasonable to have an AMF suppress - just as it suppresses magic items - the consciousness of petrified creatures, giving them peace as long as they're in the AMF. There's certainly no RAW against it.

That seems right.

"On a failure, the creature is petrified until freed by the greater restoration spell or other magic."
