If you're looking for a French symphonic organ, Caen from Sonus Paradisi should be at or near the top of the list, and St. Maximin, a late French classical organ, should not even be on it. Caen and Metz are the best large C-C options, in my opinion.
Personally I like Caen better and find Metz a little tubby -- heavy foundations and not enough blaze. Others will disagree.
You mentioned "versatile", but French historical organs were generally not eclectic. Caen or Metz will handle most Romantic and 20th century music that doesn't need a Tuba solo or a lot of strings, but aren't quite as versatile as something like the Hereford Willis from Lavender Audio or the Salisbury Willis from Milan.
(But if you were looking for French classical/baroque, St. Maximin is the only one on your list, and is great, but you should also consider St. Michel. Those pedal limitations are part of the French classical tradition and that's the intended music.)
