Should I use the JR Pass or buy tickets for a 14-day trip? W are a family of 4 traveling to multiple prefects

Hello, I would like to see if you can help me determine what would be most convenient for my trip. I will be traveling to Japan for 14 days with my family, consisting of 4 adults. We will be visiting different destinations as follows:

Day 1: Narita Airport to Tokyo (from day 1 to day 3, we will be staying in Tokyo).
On day 4: We will travel from Tokyo to Kyoto(we will stay in Kyoto from day 4 to day 5).
Day 6: We will travel from Tokyo to Osaka.
Day 9: From Osaka to Nara and back to Osaka.
Day 10: From Osaka to Itsukushima Shrine, then Okunoshima, and back to Osaka.
Day 11: Osaka to Awaji and back to Osaka.
Day 12: We will travel from Osaka to Tokyo.
Day 13: Tokyo to Ghibli Museum and back.
Day 14: Tokyo to Narita Airport.

I would greatly appreciate knowing if it would be better for me to purchase the 14-day JR Pass or if buying tickets directly.
Thanks in advanced
