Java and C# seem to be the best ways of making code-first OpenAPI based servers.

C# LINQ also seem to be the best compromise between ORM and raw SQL queries, although I never used it myself.

I have been severely disappointed in all similar solutions for Go at least and I imagine Rust does not have something better given it has a smaller community-base.

Python and NodeJS have some very neat solutions for this stuff too, but both are "slow" dynamic languages. I personally dislike python with a passion and NodeJS stuff is extremely community-driven and therefor often unreliable. Prisma (NodeJS ORM) for example just did a major overhaul and is now pushing a completely different API.

If you are making boring REST API to SQL Database it seems like Java and C# are the best options.
