The purpose of your visit fits tourism (this is the what you should tick on the application form).
You will need to supply:
In addition to the normal requirements (photo + application form + insurance + passport).
Your passport should be valid for 6 months after you intend to return.
You are a high risk applicant - therefore you should demonstrate significant ties to your home country before applying.
There is only one short stay temporary visa (the "Schengen visa"). The difference is the documentation you need to provide for the application which depends on the purpose of your trip - but the visa you get (for short trips) is the same.
