Are Regional Passes longer than 7 days?

Hello,
The 3 members in my family will be traveling through Japan in March 2026. We will be making side trips while staying in each city. Our itinerary is:
Tokyo 3 days
Kanazawa 2 days
Osaka 4 days
Fukuoka 2 days
fly from Fukuoka back to Tokyo
Tokyo 3 days

I was going to purchase the Osaka-Tokyo Hokuriku Arch Regional Pass. It seems like it would get me to most of my cities. The concern that I have is that I need the pass longer than 7 days. Is there a 14 day reginal pass option?

Will the above mentioned regional pass allow me to travel to Miyajima?

I would assume it would be most economical to purchase the ticket to Fukuoka separately. We plan on traveling to Kumamoto while in Fukuoka. With both trips on our itinerary, would it be best to purchase another regional pass or purchase each ticket individually?
