Sugar-fine is a pain. Really best for super-low flow tanks as you've discovered.
Ocean Direct is my favorite live bagged sand....nice mix of fine and medium. I've had upwards of 80x turnover via Tunze 6045's and not had any issues with it.
Also, don't sweat over the Jawfish's sand requirements, IME. Even if there's no sand at all they will make due with shells and bits of rock. It's a myth that they need super fine, or soft, sand. They don't "need" sand at all and seem quite good at adapting to other materials to make their caves.
Hahah....define "real live sand".
I wouldn't get a belly ache (so to speak) over using bagged sand. I even doubt you'd want sand straight from a beach - without cleaning and curing it would be foul before it got to your tank just like live rock. After cleaning and curing, how much better is it than just using bagged sand and adding some coral or other "seeds" to the tank? See if the LFS will give/sell you a scoop of "crud" from the bottom of their live rock bin - I've seeded tanks this way a lot.
"Live sand" is generally overrated IMO. Maybe go for it if you have extra budget. I think GARF sells it.
Good luck!
