what do i say in a job interview??

so long story short i was fired from my last job recently and i believe it was wrongful termination because almost everyone at my job was related to each other and when an incident happened where my coworker and i got into an argument, they sided with her because she’s the daughter of one of the higher ups and fired me even though i told them what she had done to me. so now my question is, in upcoming job interviews, what do i say when they ask why i left my old job???? do i tell them exactly what i just wrote, or do i just tell them i was fired, or do i lie and say i wanted to pursue new experiences, please help any advice is appreciated!!!
