You don't say anything about what you are building or what stage you are at. Your tech choices should be driven by your business needs. Some startups can get by with nothing other than Wordpress for a while. Others may need all the tools above.

I will say as far as Auth that if it's going to be important to your business and you are planning on having a ton of users then you should either choose a platform with it baked in or you should leverage a provider such as Auth0. Auth0 cost-benefit will be positive for almost any business except one that registers a ton of low-value users.
