Econometrics vs Computer Science Major Job Prospects

I'm currently an undergraduate student studying Commerce/Economics with plans to major in finance and econometrics but I'm a little lost as to whether I should continue in my current degree or switch over to Commerce/Computer Science. They would both take the same amount of time so length of degree isn't really a factor I am considering right now.

A bit of background: I am not very far into my degree as I only studied part time through my first year and I have not touched any subjects in the economics part of my degree. I worked in accounting as a junior full time last year but realised it was not my thing and although I haven't fully decided what I want to do at this stage i am thinking of working in either quantitative analyst type roles in the banking/finance industry, or data science/analytics kind of roles (sorry if my descriptions are vague are a little vague, I only started looking into possible future career options recently).

I want to keep the commerce side of my degree as I am interested in finance but am unsure of whether to supplement this with a computer science or econometrics major. I am decent at maths and have programmed a bit before (although I've forgotten most of it). Which one would be more useful considering the types of roles I am interested in? I'd love to hear any opinions/experiences people have had.

Thanks in advance
