Now that Euclid has been launched and while we are awaiting the first results, it is a good time to develop a practical sense of what insights the forthcoming data can provide. This paper presents a superb tutorial comparing the information derived from different tools, ranging from classical (e.g., two-point correlation functions and Gaussian statistics) to topological measures (e.g., Minkowski functionals and Betti numbers) using realistic cosmological models that are constrained by Planck data.
