1) Founding arc - simple, direct, everything comes full circle w/ Ymir and the Founding Titan

2) Paths to Freedom arc - nice reference to the Paths, underlines what the series has been about

3) War for Paradis arc - descriptive w/o giving too much away, nails home that this is the end

I would say Rumbling arc but that seems to be a bit too spoiler-y to work.
