For myself, it's learning the different techniques that's for sport and the ones for street
Thats a good way to look at it. I learned Boxing for that reason but realistically I should be able to use many different techniques and methods to be truly balanced and proficient.
That’s why I found myself looking up martial arts from different countries to see what might work for me. I like a lot of them honestly I just want to study and learn and use it for meditative and self defense purposes. I’ll have enough techniques to use for sport or street like you said.
