Training for a vocal dog?

Hi all! I have a 6mo male yellow lab. Very sweet and super smart. He is veryyyyy vocal. Barks when he’s bored, barks when he wants something from you, barks when he’s excited. Anything, he’ll bark at. We’re currently working on impulse control, which is non existent for him unless I have treats. He knows the “wait”command. Any training tips to help him tone down the vocal -ness? I don’t want to make him stop barking for certain things (I have to go potty, there’s someone here, etc.), but any training tips on to stop barking when he’s bored or when he wants something? I’m currently trying the “wait until he stops barking, then give him what he wants” which sometimes works. But again…impulse control. Is this something he’ll grow out of?
