The last part of your post made me laugh lol, what can you do at the strongolholds though? and where apart from the strongholds would be a fitting place for an orc to settle??
Hmm... Well, you can challenge each of the stronghold chiefs to a fist fight. You win some gold, and their respect. If you beat every chief in a fist fight, then at least you can say you're the toughest Orc in Skyrim. Being an Orc, they let you into the strongholds right away, but they may not all accept you right away. You are what they would call a "city Orc".
Alternatively, you can chat up the locals in the stronghold, (some can become companions). You can mine for
Orichalcum ore in the mines, and then forge new armor and weaponry with it (Orcs are the best blacksmiths in Tamriel!)
I enjoy going into the wilderness near the strongholds and hunting. Then I bring the food back to the stronghold and cook/eat it. I leave what I didn't eat for my Orc brothers and sisters. As another poster said, a certain stronghold is the start of Malacath's daedric quest. Can't remember which one... Bah! Doesn't matter; just visit them all!
