David Li commented on ARROW-17289:
----------------------------------

Overloads to the existing functions that take {{const DataType&}} might be 
reasonable for convenience

For docs, we should promote the cookbook more - this could easily be a set of 
recipes there (that would hopefully get indexed)

> [C++] Add type category membership checks

> Currently, type categories are only available as vectors, e.g., the category 
> of integer types is available via `arrow::IntTypes()`. This issue will add 
> type category membership test, e.g. `arrow::IsIntType(type)`.
