it depends how you want to grow. if you want to be really deep on one subject, a larger company will get you that more easily since teams tend to be more siloed and focused. if you want to learn a breadth of things, jump from data to backend to frontend to devops, a smaller company will be better. if you want to grow in training/mentorship/leadership abilities, high growth small company will give more opportunities but nobody to help you, whereas a high growth team in a large company may be much better supported to train you how to mentor/lead(there should people that can mentor you).
