Family boxing, of course. Whether it is fighting or fitness, it is good. Family boxing at the same level is definitely not good. If you learn internal boxing, I recommend you learn Xingyiquan. You can also learn from Yang Tai and Tai Ji Chuan, because practicing Xingyiquan is too tiring, and Yang Taiqi can help you very well. You can't learn Chen-style Tai Ji Chuan without esoteric acrobatics, so you are not advised to learn Chen-style Taiji.
