In that case, you should probably still default to 2by4’s, I didn’t have much problem with getting enough firewood, also if you’re smart you can avoid wasting wood for light if you do most things you can with natural lightning.
And if you’re only doing a short few minute craft like boiling water all you really need is a splintered wood or two. Sure, they burn out very fast, but it’s not like splintered wood has that many practical uses.
Also, you can haul items along the ground using backslash, a single tree should give you around 10 logs from my experience and those should last you a while, it should only take a few hours to chop the tree into logs and haul them back to your base.
I still think prefer 2by4’s since they are more convenient to use. Just take a shopping cart to a nearby building, smash the furniture and you’ll have enough planks to last you for a good while, especially if, again, you’re good at using natural light and only using fire to cook or craft when it’s necessary.
