Let's talk strategies

I'll be honest I feel overwhelmed with all sorts of strategy that's there. I personally invest in small, mid, large cap+ nasdaq MF. And I'm aware there's so many strategies like Value, Growth, Value-Growth, Contra etc. But momentum is something that EVERYONE talks about although we aren't in a bull market rn to rip the benefit out of it. So should I allocate some capital in momentum if not momentum then which strategy. (Please rather just tell me pros and cons of all the strategies) I have some capital which I wanna deploy but I'm so overwhelmed with what price shall I buy, should I buy stock or just buy etf of healthcare or realty, or go with momentum etf or something. I'm really losing my head in analysis paralysis.
