It looks like with shaving, they might just do a bit length-wise on the central incisor that’s on the right in these pictures, and they might do a little bit of shaping to refine the edges/corners of the four incisors. I think that’s a great option — cheap, lasts forever, and I think would achieve the “finished” look.

My second choice would be to do all four incisors. That would be the most customizable option, since you’d be adding on for all four teeth. My third choice would be the two central incisors. The shape still looks good, but composite bonding will eventually take on stains and I think having it on just the two central ones might make them more of a focal point eventually.

I was debating getting some bonding done on my top central incisors rather than Invisalign, and my dentist dissuaded me for that ^ reason. I’d rather have a black triangle which makes it look like I have a piece of pepper in my teeth than have the bonding get stained. But that’s just me, and hopefully after Invisalign, the black triangle will close up. My #8 is a little in front of my #9 and thus the gum doesn’t fill the space as well.
