xvimbi is right. On the other hand, if you want opportunities to explore articulations, then the Baroque repertory (Bach, Scarlatti. Handel Duphly, Couperin, Rameau, etc.) is the place to start since articulation was the main expressive device in Baroque keyboard music. It will also develop your musicality since the composers left precious little performance directions in this area, which means that you are faced with a miriad of interpretative decisions at every bar.
Good luck.
Best wishes,
Bernhard.
