This is true. Even if the bird is quite severely clipped, things can happen. It's a nice image to stroll around the marketplace with a bird on the shoulder, and I admit to being tempted (our birds are clipped, although not severely. The GCC can cover a fair amount of ground even clipped, the Cape is a bit less swoopy).
If you have a good bird store nearby, you could go observe some of the birds and see what appeals to you. I think, to paraphrase a famous horse trainer, in the end you better pick a bird you like to see and be around, because he may not be able to do all the things you want him to do, and he'll still be yours! No matter how hard you try to select a bird to be likely to do all the things you want, even if you are the best of trainers, you might wind up with a mute African Grey, or a clumsy 'tiel or maybe even a Green Cheeked Conure that doesn't like to play!
Is there a reason the fetch trick is particularly important to you? I wonder because you emphasized it quite a bit. And what you are suggesting specifically, being able to teach it object labels so that it verbally recognizes a wide variety of objects when asked, is a pretty advanced linguistic skill. You might need a better-than-average African Grey for that, plus a lot of training, and pretty advanced training at that.
Green Cheeks are fun little birds and they can learn tricks. They are quiet and a very manageable size. Ours has a modest vocabulary, but a real inclination to talk. They can be nippy, but I think that's fairly easily managed. They aren't what you'd call the intellectual parrot, though... they are kind of the party animal type.
Greys are the Brains of the bunch. Capes may be in the same ballpark, but the jury is out. Amazons also have good talking ability. Quakers are supposed to be really cool little birds, but they aren't legal to own in all states (mine being one of those).
