Which JR pass type suits my trip?

Good day dears,

I am planning to buy a JR pass and confused about the pass type, for sure I prefer the green pass for more comfortable space specially that my kid will be traveling with us, therefore if I am planning for the following plan;

OSAKA 5 nights
a round day trip to Hiroshima
Kyoto 2 nights
One way from Kyoto to Tokyo
A round day trip from Tokyo to ousuki station

Do I get the full benefit off the green pass as I heard that the green cars are limited on the bullet trains that covered by JR pass for the above destinations.

Please help so I can decide the best type.
