Well, depending upon how much real sun you get, an african violet would be office friendly. They don't require much more than indirect sunlight, though they do prefer a north or east window. You will also need two in order for it to flower.
The easiest indoor plant I have ever come across is the philodendron. Here's some photos. https://www.greenlagoon.com/Philodendron.htm
I keep the vining variety myself: https://www.fertilizer.com/garden/houseplants/philodendrons.htm
You can find them a dime a dozen nearly anywhere, you can just keep wrapping the vines in the pot, or clip it, if you need it to stay a certain size. They need water once every two weeks it seems, and just a little of the blue juice seems to keep them happy.
Another plant I came across recently is called Grandpa's Pipe. Be warned tho - I took home a little 4" plant and in two months have an 18" tall (and wide) plant!
