Hello Judo sub. A noob is checking in

I am a 37 male looking for a martial art to indulge in with my 15yo son. We DO NOT CARE ABOUT COMPETING. Primarily picking up a martial art to bond with my son , build self defense and fitness. It seems striking is not apart of most curriculums but I’ve searched the web and came across atemi waza. I’m a little confused. Is striking apart of judo or not? Is it effective? Can someone give me some insight?

Also to note, I’m looking at Judo , Muay Thai or an eclectic martial art. Pretty much a complete system preferably. If you have any recommendations, I’ll take them. East coast of US if that matters.
