After CSA, you can go through scripting and development concepts as it would help you with any ServiceNow modules that you would be working in future,

Make use of your PDI to full extent to practice what you learn as hands-on would be the most essential part of your learning phase

Register with ServiceNow University and go through course contents.

Developer learning plans are easier to understand the modules compared to official documentation and would recommend to start learning in phases, start with New to ServiceNow and later ServiceNow Administration followed by ServiceNow Application Developer,

Go through ITSM and Application Development Fundamentals on-demand courses and get certified in CIS-ITSM and CAD. After this, you can learn ServiceNow modules based on your background, expertise and interest in the domain. For example, if you have Computing and Networking experience, ITOM could be best fit. If you have expertise in License Management, Software Asset Management could be logical next step.

If you need any help, you can post in communities and experts can guide you. There are lots of YouTube videos available depending on your topic of interest and thousands of useful blogs available in ServiceNow communities. You can search in communities and YouTube and follow what suits your learning style the best.
