Review Comment:
nit: maybe we can check if `input_schema` contains any dictionary type and
use `InListExpr` if so?
Unfortunately dictionary type is treated as a logical type in DF, which
caused many issues like this before. We created
https://github.com/apache/arrow-datafusion/discussions/7421 but haven't got
resources to work on it yet.
