Education in college versus university

I want to gain a broad range of skills in construction, engineering, and health and safety, including cybersecurity, for distance and remote jobs. Beer making would be optional. Alongside a degree in biology and chemistry, I want to keep my options open with the Open University and pursue a degree in the same subjects. Still, I want to align my work experience specifically with biology and chemistry in fields that don't necessarily require a science-based degree. Still, it's optional. I want to crank it up a notch to a PhD or a master's degree program. Still, I want my work experience to align with jobs in cybersecurity, and with the fields biology and chemistry majors usually go into after they graduate, which, paradoxically, don't require a university degree.
1) Which science-based jobs don't really require a university education to pursue?
2) What jobs out there fast-track me into a science-based degree with applicable experience on a ucas statement for university?
3) How do I broaden my educational horizons and keep options open whilst also studying at university or taking applicable work experience for the degree later on?
For instance, would life sciences be difficult?
