The main purpose of ice cold beer is to hide the fact that it's not very good. I prefer beers that taste better as they warm up a little after being poured from a bottle into a glass or mug. The only canned beer I have found that's worth drinking is Guiness with the nitrogen capsule - it's pretty darned close to Guiness in the pub in England (which I've heard is different from Guiness in the pub in Ireland, but I can't personnally atttest to that.
Current favorites are Bridgeport IPA and Boulevard Bully Porter.
I’m a recovering alcoholic, so I’ve been on the wagon for some time. My beer of choice back in the day was Trois Pisoles. Fin du Monde was a close second. I only drank domestic light beers in college, for the most part, because, you’re right, they’re terrible once they’re warm.
