Hey everyone! I'm a newbie in woodworking and I'm currently working on a set of cornhole boards that I stained with a pretty cool pattern. The wood I'm using is CDX, which has quite a few knots, and some spots have cracks or crevices that are up to 1/8 inch deep. I'm wondering if I should just fill those gaps with several layers of polyurethane, or if it's better to go with epoxy (like Total Boat Table Top) for the top coat. Any advice would be greatly appreciated!

I’d definitely recommend using epoxy. Polyurethane is generally too thin for filling deeper cracks effectively. Good luck with your boards!
For filling in the cracks, go with either clear or black epoxy. It’s great for that. Just keep in mind that epoxy can scratch easily. You might want to finish everything off with polyurethane afterward to give it some durability.
If you’re aiming for a clear coat, I suggest using epoxy resin to fill those cracks and then topping it off with polyurethane. It gives you a nice finish, but make sure to sand the wood filler flush first before applying anything. Also, when choosing plywood, just a heads-up that CDX isn’t the best choice for woodworking. If you're in the US or Canada, try looking for ‘Underlayment’ or ‘Sanded’ plywood for a better finish.
