Based on some googling, various sources indicate that 35mm film has a usable resolution somewhere between 4K and 8K video, so we're arguably reaching the limits of what we can extract from it (without consideration for "AI upscaling" and such).
Cinema grade digital cameras, like the RED V-Raptor[0] (MKBHD behind the scenes[1]), can now shoot 8K footage at 120+ fps with 17+ stops of dynamic range. As far as I can tell, those specs are objectively more capable than what you can get with traditional 35mm film. It has taken quite awhile for digital to outclass film across the board, but I think we're at that point now, and the results from these cameras are spectacular[2].
At this point, it's probably a question of how much storage you want to use and whether you have enough light in each scene to shoot at high frame rates like that. (120 is an even multiple of both 24 and 30, so you can always produce 'cinematic' frame rates just by throwing away other frames, without any stuttering, but then you have the option to remaster into higher frame rates in the future if low frame rates fall out of fashion, and you can easily add slow motion effects in post, as long as the final frame rate is intended to be less than 120.)
I'm far from a videography expert, but it is something I find interesting.

It's located in a beautiful park and the nearby Nordiska museum is also quite impressive.
