The Scala 3 requirement really does cripple the choices available. The Scala 3 transition does feel a bit like the Python 3 transition where major libraries and frameworks are really dragging their feet on transitioning because of the high level of effort for very little obvious improvement. Scala 2 is still getting regular updates so there's no rush to use 3 just yet, I'd recommend picking the framework first and using the Scala version they support. That makes the development experience much better with access to much easier to use frameworks like play or finatra.
