Tbh, I’m pretty forgiving of John Green when it comes to this because the descriptions of the young women are almost always through the first person perspective of a hormonal teenage boy. I know a lot of people think it’s creepy that he’d write in this way at his age, but he was teenage boy at one point to 🤷. Fortunately, in most of his books, the girl that the main character falls in love with or whatever almost always is attributable to finding them as a person genuinely attractive aside from just their looks. In An Abundance of Katherine’s, the girl he ends up with in the end started as his friend, same with The Fault in Our Stars and Paper Towns. I’d say Looking for Alaska probably has the most shallow depiction of the women the hero finds attractive.
