Ask HN: Resources to prepare for starting a new job

Starting a new job in a few weeks and it's been almost a decade since I've done so. Looking for recommendations of books, articles, frameworks, etc that can help me to prepare. It's a product leadership role so I'll have to come up with a 30-60-90+ day plan or something like that. I'm interested in materials that are specific to product or are more general leadership or management focused. Thanks for any suggestions.
