Most hi-res audio is being sold as digital downloads. I don't think there's a currently-sold physical medium that contains digital data that's higher quality than a CD.

SACD (DSD format) is higher than CD but still not as high as 24/96k available on sites like Qobuz.

SACD, HD-Audio, Blu-Ray Audio.

I own music only discs in each of these formats. I think the last Blu-Ray Audio disk I bought (Yello Point Dolby Atmos release) was shipped in 2021.

Granted, they are fairly sparse. That disc was an import.
