Personally I do as 10 Wheels suggested, just ride at the natural cadence. Until I want to train at a higher cadence for some reason, which does happen. Sorry if that's more vague than you wanted,but it's my best take on the question.
FWIW, I use cadence in my personal training program based on Relative Perceived Exertion.

I use cadence to chose gears to maintain my desired exertion.

RPE = 6, resting... Jim's scale = 10 to 20

RPE = 7, very, very light... Jim's scale = 20 to 30

RPE = 9, very light... Jim's scale = 30 to 40

11, fairly light...50 (my usual happy-go-lucky pace without thinking about it)

13, somewhat hard...60 (I have to focus to maintain)

15, hard...70 (I start breathing hard at about 30 seconds)

17, very hard (lactate threshold; breakpoint between hard but steady
breathing and labored with gasping)...80 (my predicted max HR)

19, very, very hard...90 to 100.
My basic training is to ride at my RPE of 50% for six miles to warm up, then cruise at an RPE of 60%, and do intervals (on hills) at 70%. I try to change gears to maintain a cadence of about 85-90 rpm on flats and rolling hills, and about 60 to 80 rpm on harder hills, to maintain my RPE. Shift up to higher gears as the cadence rises,and shift down as the RPE increases.
