I should point out that it is true that option three produces more stat arrays with an 18 in them, but you're building a character needing Wis, Dex, Str and Con, so I think option two is outright better.
As a build, I'd strongly consider a TWF unarmed fighter. With MoMF, you can take multiattack and multiweapon fighting as feats, so you get the whole effect much cheaper than a normal TWF fighter. Also, as an unarmed swordsage, you can get a lot of bonuses to damage that are per hit (Desert Wind maneuvers are cheap, and don't forget Assassin's Stance and the Shadow Blade feat). Then add at least the first two levels of Bloodclaw Master and Warshaper 3, and you've got a great little hitter. Bloodclaw master makes TWF have no to hit penalty, and gives you full strength bonus on more or less every attack. Pick Tiger Claw as your discipline focus choice, and you'll get lots of extra damage on your claws as well as your unarmed strikes.
Each hit will be at without penalty. You'll get up to 5 unarmed strikes at your full attack bonus (haste, raging mongoose, TWF), however many natural attacks at -2 (don't forget your warshaper weapon), and two attacks for each iterative BAB.
Each of these attacks will have full +Str damage (Bloodclaw master) +Wis damage (Swordsage discipline) + Dex damage (Shadow Blade), and possibly sneak attack damage (assassin's stance). As well as magical bonuses and maybe +3d6+level from a desert wind boost. Also, the base damage of a monk/unarmed swordsage will scale up as you take larger forms, so you could end up with truly ridiculous base damage as well.
I'd think a BAB-improving splash of Lion Totem Barbarian would round it out nicely. Pounce is so great with bounding assault, I can't praise it enough. If that's no good, then pouncing charge will have to do
Here's a suggestion. You could drop the barbarian and 2 levels of Bloodclaw master if you wanted the space. You could also put BCM (earlier) into the swordsage side as it increases initiator level, but only if there was a base class you wanted on the other side instead.
Unarmed Swordsage 20 // Lion totem Barbarian 1 / Wildshape Ranger 5 / MoMF 7 / Bloodclaw master 4 / Warshaper 3
