Is taking Sanyo Sanin Area 7 day pass x2 worth it?

I am very confused as to what type of travel pass I should purchase from the range available. Your help to understand if I should go for a full Nationwide JR Pass (and which of the 3 possibilities: 7, 14 or 21 days) or go for a combination of the different regional JR Passes mentioned under https://www.japan-guide.com/e/e2357.html, I could use, would be greatly appreciated.

Hello everyone. I am really confused with the price increase that happened since last October 2023 if purchasing a nationwide JR pass is worth it. I was told it would be better to purchase regional JR passes.

I was told that the JR Sanyo Sanin Area Pass primarily covers JR trains within the Sanyo and San'in regions of Japan, which include cities like Kyoto, Osaka, Hiroshima, Kobe, and Himeji and would allow us to take the Tokaido-Sanyo Shinkansen as part of the Sanyo and San'in JRP to travel from Kyoto to Hiroshima. If this is correct then would you advice me to take the JR Sanyo Sanin Area 7 day pass x2 (23,000 x2 = 46,000 yen total) that would cover us for our 14 day planned travels from 28Jun-11July listed below?
