FPS locking is not the right solution (although it is an easy one). Your animations are the ones that should be animated on twos, or threes, or fours, or whatever feels right for your game. That applies to animations, particles, etc. This leaves you the option to let other things run as fast as needed to feel smooth (for example: I do like the leaves falling slowly, the book opening, etc. Camera panning & moving would feel infinitely better at a 60 FPS.)
Unfortunately, playing a game is very different experience to watching a movie: take the example of Ghost of Tsushima, that despite having a Kurosawa mode, still accepts 60FPS and over.
I have the PS4 version (yes, base not Pro) and it's 900p-720p dynamically switching and 25fps, maybe 30 in better cases. Which is utter trash. It's like watching movies in 360p on Youtube. Or listening to music in 64kbsp. On top of that the story doesn't save the game either which is mediocre at best especially compared to what was promised.
Then look at Ghost of Tsushima or RDR2 on the same console.

Perhaps watch a few Samurai films by Akira Kurosawa with your son and discuss the violence that happens on film in the context it arises?
It's also worth watching a couple of YouTube reviews of Ghost of Tsushima. I recommend the ACG and SkillUp reviews.
I think if you do this you'll be better placed to judge if he's emotionally ready or not.
