Want to learn more about software development

Hello People I have been working as a product manager for 2 years. Mostly I worked on the business side. Now I want to upskill myself on the tech side as well. Please suggest some ways to learn software development. I want to know more about the important things like the backend, frontend, database, cloud computing etc. PS: I don't want to become a software developer I just want to upskill myself so that I can decide on the tech aspects of the product also. Thanks in advance.
