Hello need a advise…

Hello the community I can call on you to advise me on the deployment of my new project which will be developed under Drupal 7.
This one will propose two entries under two separate urls of type:
– mydomain.com/public/
– mydomain.com/pro/

In fact I am looking for the best way to classify, from the same type contained my nodes, for example my news articles. Should I use taxonomy or simply create a select field to classify the new content.

Thank you for your reply.
