Best Economics Course for A Research Internship in International Economics?

Hello, I’m an economics major and math minor undergraduate junior and I plan on dropping one course from my schedule due to my hectic personal schedule. I’m currently taking:

Economics of Inequality

Numerical Analysis

Social Development (of nations. think like the United Nations)

Statistical Methods (Stats with Excel)

Which of these courses will look best to employers on a resume when applying for internships?
Which course is least appealing to internship employers?
Any classes you recommend I take that companies look for?

I want to do research and focus on international economics and global priorities research. Think tanks like the Council on Foreign Relations, Atlantic Council, and Center for Strategic and International Studies.

I would really appreciate the advice.

Thank you :)
