JR Pass, Regional Pass or other passes

Hi!

I will be travelling with my family to visit Nagoya for around 2-3 days and after that, staying in Tokyo for around 7-9 days around Nov.

There are 2 adults and 1 child and I was wondering if I should get JR Pass, Regional Pass or focus more on the Tokyo Wide Pass (under JR East)?

It seemed that Tokyo Wide Pass under JR East is the best option when we are in Tokyo but I am unable to reserve tickets now and furthermore, the Tokyo Wide Pass is only valid for 3 days.

Would appreciate some help and advice! Thanks!
