Favorite “Jack of all Trades” civ

Some civilizations excel at a single unit or strategy on Arabia (see Britons, Franks, Lithuanians) but others are above average in a variety of units and strategies (Inca, Japanese, etc.) I think picking a well rounded civ allows average players to learn the game well. What are your preferred “Jack of all Trades” civs? I consider any civ that has full castle age upgrades, bloodlines, and thumb ring, and cavalier To be well rounded.
