I know I have to spend money to get a quiet servo for animatronics. Not happy, but accepted that fact.
I see three that might work. Which is recommended? Torgue requirement is not that great ... blinking eyes and moving eyeballs on dragon stage prop. But must be quiet.

12 v is fine, if necessary.
Rather exspensive servos for what you want.
Bit too powerful as well.
Take a look at these.
Any servo will have noise from the commutator and gearbox.
Smaller should be quieter.
For very low noise you need a non commutated motor possibly without a gearbox for an eye blink.
These could be insanely expensive.
Perhaps muscle wire could be used . ?

...and with a nice small servo you'd have room to encase it in a square foot of sound deadening material - just extend the output shaft down a suitably thin bit of plastic pipe, then wrap the whole lot in a load of cloth. Should end up pretty quiet.
