   We created an "umbrella" issue that includes all the issues opened and connected to the Python to array conversion following the code path in `python_to_arrow.cc`. See: https://github.com/apache/arrow/issues/36202.
   
   To sum up:
   1. The first part of the issue reported which is the float truncation: as we are starting from a list the python-sequence code path is taken (`python_to_arrow.cc`) and in case of of float -> int the conversion is unsafe by default (inconsistent with numpy code path). The separate issue to track this is: https://github.com/apache/arrow/issues/36202.
   2. The second part (large integer outside of float range) also has a separate issue created (as already mentioned): https://github.com/apache/arrow/issues/35563
