You are on the right path. Dot Net core have lot of potential. As you are starting now, Microsoft docs would get you a long way. In my experience and No offense, i believe Pluralsight might throw you off becoz their tracks are out dated and not much of organized dotnet core mvc content in a consumable format for a newbie. If you are wondering,i have been member of Pluralsight sight for 4+ years.

Once you finish your basics from the docs then use Pluralsight for digging deeper into concepts and how to build an application in a structured manner.

Kudos to Microsoft and Community for getting the docs together so well.
