Youtube is great for getting the overview you need but you want to stick to more recent videos, something no older than 2 years. Based on what you have, you can support the basics of Part structure and CAD management however it depends more on the licenses you own and their allocation. If you want to get into library part management, classification and supplier management, look at PartsLink and SupplyLink add-ons. If you need to integrate with an ERP system to push BOMS and Parts downstream, there is the ESI modules, either indirect or direct for added cost (TIBCO) and those would be ERP system specific.
It also sounds like based on MBSE and Codebeamer, you are looking at software and source code management? I know very little about that. You might be able to get a series of web demos from your local PTC rep.
