Hiroshima Day Trip from Kyoto Options

We are traveling to Japan in two weeks for 18 days doing a Tokyo –> Kyoto –> Osaka itinerary. I want to add a day trip to Hiroshima, but need some help. Currently thinking of doing the day trip from Kyoto.

From what I have seen there are 2 general itineraries:

  • Head to Miyajima island first, head back to Hiroshima for peace museum with enough time before they close, view peace park and dome at night for more solemn peaceful experience
  • Arrive at museum early before crowds, stroll peace park, go to Okonomimura, take ferry for Mikajima island to enjoy serene vibes at night and take the ferry back before they end around 8pm

Curious to hear from folks who have done either (or both) of these itineraries. My main concern is that Hiroshima (for me) is the main reason for this day trip and most important to me. I don't want to feel rushed through the museum and gardens. For those that have done versions of these itineraries what were your experiences?

Also, I realize writing this in hindsight I should have booked a night in Hiroshima — you live and you learn.
