I was looking for a mature, complete and powerful statically typed stack as well. ASP.NET was my clear answer (not Go or Rust).
There's a lot of noise coming from Microsoft to sell their new products (this year: Aspire.NET). But don't be mislead by this noise: .NET Core (C#, ASP.NET Minimal API or MVC, EF Core) is more batteries included and reliable than most other options. The only gripe I have is the need to get into the OOP and DI mindset ("create custom implementations of some abstract classes and put them into DI and the framework calls your implemented methods magically" kind of stuff). Takes some time, but not a big deal for experienced devs (and younger ones can learn faster anyway :-)).
