Creative writing, maybe? Outside of founder-level product managers, of which I have worked with several who are actually creative, I remain unconvinced there is much real difference.
Product Managers - identify problems to be solved, decide/play a role into what features goes into MVP or a release, talks to customers, comes up with/designs the solutions (functional solutions) to the problems (aka features and how they interconnect), do UI designs (major UI designs can go to the UX team, smaller UI designs stay with product manager), etc
If your company is using the sprint model, the Product manager is not doing much of project management.
At the end of the day, what a PM does depends on the company and how they use PMs
As a product manager (technically "program manager" at Microsoft, but it's roughly the same as product managers across the industry), project management is one of the many things I do, in addition to the list above. But I am explicitly not a project manager in that I'm supposed to minimize time spent on that and share some responsibilities in that space with my engineering counterparts.
