Is a MSc or BSc in Information/Data worth it?

Hi! I’d really appreciate some advice. I’ve worked in ESL overseas (South Korea) since 2017 with prior office/admin experience & I’m planning a career change into information / data science work in corporate or embassy environments.

I’m currently looking at Information and Data Science courses at the University of Sheffield. I haven’t studied since 2009 & an online MSc attempt in 2021 while working full-time was very stressful.

I’m 39 y/o and trying to choose a realistic, high-employability path. From an employability perspective, is a MSc or BSc the better option, or is there a more gradual route, especially for corporate / embassy-type roles? I really appreciate any insight.
