From what I have seen, you should figure out what you are enjoying the most, whether it is sales, product, marketing (product marketing, content, perf/brand/comms, field marketing). The basics are you need to write well, be data driven and importantly curious as an internal skill. Depending on what you enjoy the most, the career gets verticalized.
Simple paths : From Content , you can easily move to manage the Content Team or Product Marketing/Product team. From Content can also move to SEO and Perf Marketing. Having said this, at junior level Sales/Product/Marketing career paths are all open.
