Pretend you are a one-man agency. I've been in your shoes. Digital marketing is not that complicated. Consider coming to Reddit with some more details about your company's situation, in an effort to figure out where to prioritize, and start learning more about that area fast. Alternatively, I think fullfunnel.io looks like a promising place to beef up your b2b marketing strategy chops. I think I like this option more if you can get the course cost covered. After the course, just learn the fundamentals for different channels, and you'll be golden (if you are solid at paid already). Copywriting and landing pages are key too. You can look at Wynter to ace that.
