Yes I think Babel is a little lighter on gorey excess than the Poppy Wars (which I haven’t read but my partner has described in detail to me). Which is to be expected for books designed to depict the horrors of colonialism.
But mainly mentioning it with a content warning since it’s often tossed around as an HP replacement. I think the first half of Babel captures a similar “wonders of magic school” vibe, although with a lot more caveats about how inequitable the entire system is. It does get extremely harrowing by the end so maybe should include a clearer warning in my post.
