I find the jobs to be done framework very useful in order to keep a customer-first mindset. Truly understanding your target audience's needs serves a product marketer targeting any segment or industry. Ultimately all buyers are people whether they're purchasing as a consumer or as a representative of their employer.
JTBD is a great framework for products with many use cases which can appear across multiple B2B ICPs. For example, when I was leading SDK product marketing, we used job stories to explain typical use cases for SDK. Our enterprise users "hired" SDK to solve their own integration needs and build various types of extensions which went into typical job stories.
