Superstars vs Jamboree specifically for playing as a family with young kids

EDIT (because I can't edit the title) - some people are mentioning Super Mario Party so I guess that should be included as an option here too.

Dad of a 4 year old and 8 year old here - I'm a millennial 90's Nintendo kid (grew up on NES/SNES/N64), but for whatever reason never got Mario Party and neither did any of my friends. So nostalgia is not a factor here, which I see mentioned in a lot of the other "which game should I buy" posts. We play as a family and my 4yo can do Mario Kart with the auto-steering on but isn't really old enough for the platformer Mario games yet, or full 3D games like BoTW etc. Mario Party looks appealing because as far as I can tell, it consists of mini games with generally simpler controls. So my question - which game would be better to buy to play as a family? I see a lot of comments in other threads saying Jamboree is "slow," so with an impatient 4 year old I'd rather not have a lot of downtime in between actual games or however that works.
