It is strange that you mention so many form of Republic, yet no form of democracy like direct, consistutional, representative... democracies (some Republics are, but it definitely doesn't mean republic = democracy).
As for me, I'd love to get a philosopher king, but this is a wishful dream, so monarchy/bonapartism (I don't like the anglosaxonism of Napoléon III though) would be ok. I appreciated the idea of Napoléon IV about making an aristocracy of merit and trying to make the life of workers better/extirpated them from slavery.
