Any of the circular options would work great!

None of them in that space. I would look for 2-3 small, perhaps nesting tables that would be easy to reposition as needed and not an obstacle when not. Perhaps 15"x24" for one or two, 9"x12 for one.

If you must have a "coffee table" then I think a round one, as small as is practical to meet your needs, would be the easiest to maneuver around.
