I recently built some DIY garden beds and realized I need to smooth out the wood to make it safer for my kids and myself. I have a bunch of Dewalt batteries, so I want to buy an electric, cordless sander. Should I go for an orbital, a belt sander, or something else? Also, it would be great if the sander has more uses too. Any recommendations?

Random orbit sander for sure! The cordless belt sanders are pretty rare, and if they exist, I’m not aware of them. For sandpaper, grab a variety pack, but I'd focus on 60 or 80 grit for quick splinter removal. You can always smooth it out afterwards with 120/140 grit, and for a super silky finish, a third round at 220 grit might be nice if you're feeling ambitious!
You can use a belt sander if you need to remove a lot of material from pressure-treated wood, but I'm leaning towards a random orbital for general use. Just make sure the wood isn’t too wet; that can make sanding much harder. I primarily use corded sanders, though, so I can't help much with cordless options!
I’d definitely suggest going with a random orbital sander. It's super versatile for smoothing surfaces and getting rid of sharp edges without leaving pesky swirl marks. A regular orbital sander is slower, and a belt sander is more for heavy-duty jobs. You'll likely end up gouging your wood if you use a belt sander here!
What grit sandpaper do you recommend for pressure-treated wood? I'm surprised how simple that sounded!

Thanks for the tip!
