Who are we?
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
We are one. We are legion. And we're trying really hard not to forget.

Digital? No. You want durable, you go physical. Print the photos with real archive-quality processes and materials. Same for video and audio, but on film. Keep a 3-2-1 backup in climate-controlled environments.
If you really really want digital, the media doesn't matter, because you'll always have to migrate to current formats. Someone will have to be actively maintaining it.
Yeah, I'd say at least every ten years I've replaced all my media. Hard drive failures, tape upgrades, physical media changes, tech just moves so quickly. Even if the media survives 100 years, will we still have the tech to read it?
will we still have the tech to read it?
Probably, if VLC is still around.
Telnet still exists and you can still access a telnet server running on 40 year old hardware
I believe you're approaching this from the wrong angle - this isn't a tech problem, this is a people problem.
save them for posterity so that it lasts for periods like 200 years and more. This allows great-grandchildren and great-great-grandchildren to have access.
Instead of trying to get media that can last 200+ years, just teach your kids and grandkids the importance of keeping your family legacy alive. This will be way more effective than any medium you can come up it. Storage technologies change but the data remains the same, the future generations should be able to gradually upgrade storage mediums as necessary so the information keeps existing.
Cave paintings aren’t video or audio. They’re pictures. You can print your photos or print grabs from your videos.
