I don't think there is a single "best" available resource which will magically transition into product management. One needs to learn about a myriad of things and then build some products to gain the concepts and confidence needed to lead product in any venture.

I will recommend you to start reading the right books and following certain folks to start dipping your feet into the product world. Ken Norton has a solid list of books that you should start reading up.

Having said this, I saw this as a challenge and a common problem faced by a lot of folks, so designed a course which effectively transitions people into a job as a product manager. The course is packed with everything that a product manager should know theoretically and first-of-its-kind pairing with an in-house developer so that students gain the experience of building and launching a product.
