Any ideas of a break out board with better spec for PWM?

What frequency are you using on the Arduino?
The PCA9635 is an option, but 100kHz is too high for most LED drivers. I don't know of a comparable all-in-one PWM chip which strikes the balance. It does work, but point a phone camera at a dimmed light - you'll see the rolling shutter bands on most drivers.
(You could get to 2.6kHz on the 9685 by driving it with a 50MHz clock, but thats pretty extreme).
