I think H.264/AVC, H.265/HEVC and AV1 all will have long-term readability. There's free software to support them. AV1 is supposed to be patent free now, H.264/AVC should be in 20 years. But: AV1 is not the one codec to end them all. There will be AV2, H.266, EVC and more. And in the future KI might offer much better scaling, denoising etc. than we have now. So for very important content it's best to keep the unfiltered source data losslessly. E.g. encode to AVC lossless solely because it may be more readable than DVCPRO in 20 years. Then store copies redundantly in the cloud and other places.

Is AV1 ready? I don't really think so. Encoders are slow and probably not as fine-tuned as more mature ones like x264 or x265.
