I spent some time experimenting with CUE in 2020 and would handily recommend it if you need something resembling "configuration with constraint solving behaviors". It can be a bit surprising in that when it terminates evaluation, you don't always have a clear mental model of how it got to that answer. But that's also the part that it does well at automating.
