I love Diesel for ORMs - it's very much in the same spirit as a type safe sqlalchemy, so it depends if you like that. The type safety is a great feature, it always saves me from writing incorrect queries (a huge one is nullability is represented as an option, so nullability mismatches are caught very early). It has an async version that is not as well maintained so it does lag behind, but I've never had an issue with it. To me personally, the Diesel ORM is the #1 reason to be using Rust for a web backend - it has saved me so much pain from having db/model mismatches since they're caught early.
The only other thing I've heard that is close in any language is C#/F# LINQ (I mean I'm sure there's random other projects, but haven't talked to other people about actually deploying backends with similarly type safe ORMs other than that).
There is axum OpenAPI at https://docs.rs/axum-openapi3/latest/axum_openapi3/, I haven't personally used it, I've mostly been doing GraphQL which I find works very well (including the N+1 problem etc).
And of course, I personally find cargo and the dependencies there to be roughly as ergonomic as python. Its dependency ecosystem for web isn't as deep as python or node.js, but it's pretty solid IMO. It may not have downloadable clients for a lot of pre-existing OpenAPIs etc., but that's also something Claude can port in 5 minutes.
