If you'd rather go through some of this live, we have a section on Stats for Growth Engineers in the Growth Engineering Course on Reforge (course.alexeymk.com). We talk through stat sig, power analysis, common experimentation footguns and alternate methodologies such as Bayesian, Sequential, and Bandits (which are typically Bayesian). Running next in October.

Other than that, Evan's stuff is great, and the Ron Kohavi book gets a +1, though it is definitely dense.
