I can attest to your recommendation. Europa Universalis, Crusader Kings, Hearts of Iron, Stellaris, and Victoria are their primary grand strategy series these days. Each one of them specializes on a different time period, either in the past or future. They all have a considerable amount of depth, but after a few hours of playing around and accepting a few losses, they're a great step up for people with experience with strategy games.
