Best breed for a first time dog owner?

What is the best breed of dog for a first time dog person?

I’ve always grown up with cats, and I love cats, I just sometimes want the loyalty and badassness of a dog. However I’m never sure which breed would be ideal for a first time dog owner; the last thing I want to do is commit to an animal and then be unsure about it a week later.

I live in a regular single family home, small back yard, but does have parks close by. I would want something thats chill for 90% of the day but does have their moments of excitement. Something smart, but not too smart, I don’t want this to turn into some sick mind game for him. Just a dog that will be fine watching TV with you one moment, however still has spunk to want to go outside if necessary. Just something that is small to medium sized, and doesn’t treat the house like its personal chew toy.

Thanks for your opinions in advance =D
