I sell hundreds of insurance leads each week, but not in any of the three categories you've listed.
My advice is to bypass the affiliate networks and sell the leads direct.
It's a bit more work, but vastly more profitable.
without giving away to much shane and trying not to steal the thread I'd be interested to know more about your process of selling leads, I know a few of us have sites for solar, electricity, gas, even plumbers etc so if you would care to share that would be great.

I've used both methods over the years and have found that the revenue share method is the most profitable, but you need to have a lost of trust in the buyer, and you need a buyer that is good at converting!
