What is the best way to go about scolding my puppy?

Since you all were so helpful in terms of recall training, I’m curious for some insight on getting after a pup who does something wrong!

First and foremost, I do my very best to consistently reward good behaviour, and reinforce positives rather than focusing on negatives. For things like peeing in the house, I essentially just rewarded every time he peed outside and the problem resolved itself. However; things like jumping on the counters, pulling things down that he shouldn’t have, and eating them, etc. are still a bit of a problem despite my efforts.

He gets lick mats, a plethora of toys, different chews for his teething, park 2x minimum/ day, plays plenty with other dogs. I don’t think boredom is a factor. He’s just a puppy exploring the world. When teaching him it’s not okay, I don’t like to force him to his kennel as I don’t want him to associate that as a place of punishment, so if I’ve just scolded him I don’t usually put him in there. He will go lay down on his bed if I scold him and not get up until I tell him to, but I also would like to be able to use “place” as a command to go take some space and lay to relax when I’m doing something like cooking.

What is the best way to scold a dog so he knows it’s something he shouldn’t do, without ruining safe places for him? Is it more a firm “no” and then go on about my day, or should I be making him lay out for a bit?

EDIT: the term “scold” is a very loose term. I don’t want to yell at my dog, or “punish” him, rather just help him learn what is acceptable and what is not. As I said, I focus heavily on rewarding good behaviour and that works a lot, there’s just certain things that he hasn’t got the hang of yet. Thanks for all the helpful advice ☺️
