There are some of the fried snacks that can be good with the beer. I have tried some of them. And they can be really good too. I'd say depending on what you prefer it can be different for each one of them.
I love to smoke a cigarette while drinking beer. Although nuts taste great with beer. Anything that has a little salty in taste would be perfect for my enjoyment. I would never eat that much as it might cause vomit.
I am not a big barbecue person but I do agree that it pairs well with a good beer. I like the dark lager types with a good slathering of BBQ sauce.
Actually I really love drinking beer with foods, especially the salty one, because it is just like a perfect match in my taste.
