I am only familiar with the Huron design thru the online pictures on the Glen-L website. If you leave the screws in, and they are sunk deep enough, the bores can be filled with a mixture of epoxy thickened with sanding dust.
I suggest you try it on some scrap to see how the colour will look.
If you have stripped screws, I would just fill the holes. I would not bother replacing them with larger screws.
If you want a nice natural wood (bright) finish.... and assuming you epoxied the planks down well, another option would be to remove all of the screws, bore the holes in and fill them with bungs (wooden plugs).
Here is a picture of the bungs I installed on my deck.
