It is all depends of your goal with the project. GPIO7 isn't available, so you need to choose another one, but I can see that you mentioned GPIO1 too, which is the UART TX, so you won't be able to get Serial outputs such debug traces if your use that one. I would choose another one there too.

This can help you to figure out such things :
