what kind of portfolio projects?

Hi!
I've already picked up basic skills in Python, HTML/CSS, and Figma. Looking ahead to college, I'm torn between majoring in Computer Science or Interactive Media/UI-UX Design because I want a career that combines coding with creative visual design.

Could you recommend specific college majors or interdisciplinary career paths (like slope) that bridge these two areas? Also, what kind of portfolio projects should I focus on building this year to prepare?
