Go back to the age-old economic rule of demand and supply. Look for industries that are doing well and/or show promise or growth in the near-to-medium-term, and look for overlaps with your aptitude / interest / qualifications.
If you're not yet tied down to any specific qualifications, or are flexible and willing to change, that would open up the field a little more.
For upcoming industries, look for trends in technology sections in leading news outlets like the Times, WashPost, WSJ and CNN. For industry growth patterns and companies in those sectors, look at industry benchmark sources like Forrester and Gartner. Many of their publications may not be freely available but usually their content is syndicated out and made available by the companies that are highly ranked.

At the end of the day, however, this should depend on what interests you, and what you believe you can pursue in a sustainable career over the next few decades.
Industries that are likely to grow in the next few years and decades include anything related to Artificial Intelligence (AI), Robotics Process Automation (RPA), IoT, Blockchain, Digitization.... something more out there but immense potential
