The AUDITORIUM shape is my favorite and the majority of the instruments I've built in my workshop, are OM size. It probably is the most versatile acoustic guitar shape on the market, since Martin & co. designed it in the 20th century.
Fingerpicking style, is the most appropriate way to play this guitar... but you'll definitely be able to strum it for amazing results. As a famous luthier said once: "this, is a responsive guitar!"
