You have Oblivion Warcry: New Dimension on your poll, however that is not part of FCOM.
Warcry, however, which is part of FCOM is a totally separate mod.
There's an overhaul comparison thread around here somewhere that lists how they differ. Which is best for you will depend on whether you want the world to revolve around the player, or whether the redesign should focus on the location and world itself, in which the player is just one more actor. OOO tends to focus more on the latter approach, while some of the others focus more on the former.
If you're looking for a FCOM-lite, then OOO is probably the closest thing since that's really the core of FCOM.
