Which jobs are exciting is a very personal question. Jobs with similar titles can be very different in practice depending on the culture of the company, how much autonomy individuals are given, etc. I'd recommend searching on different job sites like Indeed to learn about different types of jobs, major job responsibilities, and required knowledge, skills and experiences. You can also visit sites like Glassdoor to learn what it is like to work at different companies.
There are many other factors that may impact your enjoyment with a role: job security, professional development opportunities, company leadership, work life balance, opportunities for advancement, benefits, corporate social responsibility, etc.
