Surprised I couldn't find an answer to this on Google. For transferring a complete dataset (polygons, in vector form) in a single file, what is the most size-efficient file format?

My experience is that databases (geodatabase, sqlite) handle large polygon layers better in both disk space size and performance compared to file based (e.g. shapefiles). In addition, for geodatabasees you may further compress them, see link below.
