As funkyanarchy said in their comment, our individual consumer choices have very little impact on capitalism and ecological devastation writ large. I don't say that to try to dissuade you from your choices, but to hopefully make easier the reckoning with the reality that one can not really drop out by half measures.
If you are choosing to have a cellular phone, you are choosing to be using technology developed by very large and terrible corporations, running on a device and infrastructure predicated on slavery and exploitation of the earth. I don't say that to sound harsh, it is just a reality. A used phone perhaps mediates that, but it certainly doesn't negate it. The same is true of most of the other lifestyle choices you mentioned. The same holds true of computers, cars, etc.
Knowing that, I am absolutely not discouraging you from making the best choices for your situation, but to recognize that those choices are going to be more about your feelings than the actual impact on various systems of oppression and exploitation. One of the traps that people can fall into very easily is seeking out some sort of total anarchist purity, and the truth is there ain't no such thing so long as capitalism, civilization, and the state continue to function.
I would encourage you to think about those best choices as situational, and based on your own ethical, or (eww!) moral framework, meaning that you playt the best you can with the cards you were dealt at each hand (example - I hate Walmart, because they are terrible. I have been shopping in a Walmart in the past month because it was what was available and met my needs in the moment. I did so with no fear of going to anarchist hell or being denounced, because I know that anyone who denounced me would not be an anarchist whose opinions I value).
PS - I don't have Netflix, so I don't know. Someone I know just gave me their ex's mom's Netflix log in and password, so maybe now I do have Netflix? I haven't tried it yet.
