I can recommend "The Mind Illuminated" by Culadasa. It presents a path for meditation in ten stages, describing in simple and clear language goals and techniques for each. There are both directly actionable advice for many different circumstances, challenges, etc., and more theoretical / philosophical discussions for context and understanding. I have followed the system described in the book for about 15 months, and think it had a positive impact on my life and my well-being in general.
