I think there is an interesting YouTube series up by Jesse enkamp who kind of builds the theory that karate was more of a grappling martial arts but kind of got turned into a boxing sport when the Japanese adapted it from Okinawa. They already had Jiu-Jitsu and were kind of looking for another martial art akin to boxing. Basically Jesse visits China, finds people showing him Kung fu katas that resemble goju ryu katas. And their explanations about what the katas describe supports the “grappling” theory. For me who trained goju ryu a s a kid it was eye opening and I think makes a lot of sense
