A champion 2000i inverter generator would do it all but the AC and do it as quiet as the other two options do it, just less expensive. Get lucky and you can find them on craigslist for $3-400 and supergen usually has refurbished for $499.
As far as Champion being junk, what about dependable, easy starting, quieter than other open frames makes them junk? I've had a 3500/4000 for years. it can run our AC 2000 ft higher than a Honda 3000is, starts in any weather with one pull, and be as quiet as a Honda Handi with a sound tent.
The best part is that by NOT wasting my money on a pretty generator that can't at altitude, I used it to buy the solar and batteries that allow us to leave the generator at home while still having all the comforts of hook ups.
The dirty little secret of all of this is that you can buy the quietest generator made or like us go solar and be silent only to have the neighbor pull out the loudest open frame or think that his Honda is SOOO quiet that it is ok to run it 24/7.
So with that thought in mind I can tell you that our Champion 3500/4000 has never been heard even when we did use it. We only boondock and we can barely hear it inside with the TV and AC going. Outside I'd want a good 100 feet or better to drop it to just annoying.
No generator is quiet enough for close quarters.
