Github Comment:
We recommend {{{}Arrow::arrow_shared{}}}. So this change is preferred.
FYI: Users can still use {{arrow_shared}} with CMake 3.18 or later for backward
compatibility.

[https://github.com/apache/arrow/blob/master/cpp/src/arrow/ArrowConfig.cmake.in#L110-L121]
BTW, we have a Jira issue to update this document: ARROW-17575
If you take over this, I'm very happy!
Here are some notes for the new our CMake packages:
* Users can use {{{}find_package(Arrow){}}}, {{find_package(Parquet)}} and so
on as usual but can't use {{COMPONENTS}} like {{find_package(Arrow COMPONENTS
parquet)}}
** The old our CMake packages just ignore {{{}COMPONENTS{}}}.
* {{Arrow::arrow_shared}} is recommended than {{arrow_shared}}
* {{CMAKE_PREFIX_PATH}} not {{PKG_CONFIG_PATH}} should be used to find Apache
Arrow C++ that isn't installed to the system location such as {{/usr}}
** The old our CMake packages also uses {{PKG_CONFIG_PATH}} ({{{}.pc{}}} can
be used to find the {{Arrow}} CMake package)
> [C++][Docs] Update build document to follow new CMake package
