Hi, Best jobs like by introverts are those with less to no social attraction in it, an independent, to oneself jobs.
As in scientist/researcher is the best that also pays well and most independent one while there are more eg, Computer programming, Archivist, Graphic designer, Researcher, photographer, video editor, Social media Manager etc. computer programming pays well and you also have more sub divisions in it which gets more and more isolated as hacking, web development, web designing etc.
