I use a light bit of beard wax to tame the fly aways. Brush frequently to 'train'. Your beard is as unique as you. Let it find itself with just a little help from you. Let it grow and don't obsess. Beard on!
It hangs about 2 inches off my chin, but the hairs on the front of the chin are around 4 inches. I actually just cut about an inch or so off the chin this weekend to even things out. I trimmed down to a ducktail in the spring and started growing the cheeks back in about a month and a half ago. I mostly just put some beard oil in after my morning shower and comb it down.
