Welcome to the site! Most commercial sauces are going to include HFCS since it is cheaper than sugar. I suggest you try making your own sauce. It's not that hard. I see onexchef has already posted a recipe that sounds like a good red sauce. Try some out in small batches and then start tweaking the recipes to suit your preferences.
Next... What do you want to sauce? Are you going to sauce ribs while cooking or serve sauce alongside your pulled pork? I don't sauce anything during the cook but frequently sauce when I reheat or serve. One of my favorites is Big Daddy's Carolina style BBQ Sauce
which I server with pulled pork. I like Raichlen's Red Eye Sauce
