The safest thing is of course not to use anything. Who is to say that a strong smell from vanilla or cinnamon or something else isn't also potentially harmful? But, I think it really depends on what is important to you, and how risk averse you are.
My impression is that scented products of all kinds are a big unknown area, but I suspect there are really only a few ingredients that are problematic, if they really are. The problem is that we don't know what they are. This is one of those areas where there are a lot of anecdotes floating around on the internet, but very little in the way of hard evidence. Anything overpowering or uncomfortable for a human would almost certainly be uncomfortable if not harmful to a bird... but ventilation plays a role as well.
I wouldn't encourage anyone to follow my example, but I have long used Yankee Candle Co hot oil air fresheners and when we first got Scooter, I didn't know such things could be harmful, so I continued using them. They don't appear to have done him any damage, and while we keep things like that well away from the office room and living room where the birds spend most of their time, I do still have them in more remote areas of the house. I also sometimes use scented candles in my studio when I'm working in there (window open, birds never in the room) and we've been known to use them in the living room when the birds have been put away for the night. The room where their cages are is pretty well ventilated and around the corner from the living room and there is no indication that the scent travels that far. I am, however, unlikely to experiment with anything new, nor use aerosols or any of these products in the direct presence of the birds. I honestly worry more about cooking odors which sometimes permeate the house despite a rather good vent fan. And we need to get our patio doors refinished, another wet winter will ruin them completely, and that's a very stinky proposition with known harmful fumes. Not sure how we will handle that yet. Possible board the birds for a few days.
