50mm would be good if you would have a full frame camera. a6000 is not a full frame one.
I have almost bought 50mm. but a friend of mine adviced to buy 35mm and it was a very good decision.
problem with 50mm is indoor shooting it very limited. as you would have to stay 2 or 3 meters away of object to make nice photo depends what is framed.
and in a room you cannot always step back 3 meters to get a desired shoot.
take 35mm or even smaller number, trust me.
