EarthDesk has a database of 10,000 cities you can choose to set as the map’s centering point. The preferences menu also includes a pop-up menu to provide information about a city, such as sunrise and sunset, moonrise & moonset, current local time, coordinates, etc

Besides a city, the centering point can also be set as 0° N by 0° E, or it can follow subsolar and sublunar points and antipodes. The map itself can be displayed as one of 11 different projections, including the familiar Mercator projection and a standard globe. You can select a Living Earth mode to simulate a view from space (sans clouds) which even shows city lights during the night. Alternatively, you can select a political map mode, displaying country and state boundaries.
