Default Venting wastegate to atmosphere?
So I have heard all the positives to venting the wastegate (boost control, no exhaust back pressure, no creep...) but what are the potential downfalls? How loud are vented wastegates with a couple feet of pipe running off them?

Very loud compared to a wastegate dumping back into the downpipe/exhaust and can make things dirty if it isn't dumping down and away from everything.

Get it dumped into the exhaust. Its fun at first but gets real old fast when you have it dumping in the atmosphere.

If you were to run a closed cutout after the downpipe into a quiet catback. Would you be able to hear the motor through the wastegate or it it pretty much just the "jet" sound?

Some people have run motorcycle resonators on their dumps. Haven't personally done any like that but most customers like the open dump over running into the exhaust.
