Welcome to the game and to the forum. 
As ya1 said, there are literally dozens and dozens of builds that can do endgame content, the dual mastery class combo gives you a lot of build diversity to play around with.
What I suggest you do is have a look in the Build Compendium at the beginner builds section. Find a class there you’d like to play and then check in the relevant section for an endgame build for that which you can respec into if needed.
The beginner guide will help you with levelling, the devotions to look for, gear, etc, and could even carry you though endgame as is. A bit of tweaking from an endgame build should be all you need if necessary.
