I'd add that with 4k file sizes, for anyone that will continue to create content, LTO is going to be your most cost effective solution.
Regardless of file size, much of the industry does not consider hard disk drives to be archival because after a year or more of shelf storage, you can't always count on a drive still spinning up. IMO, LTO is the defacto media for long (30 year purported) archival life. With the advent of LTFS it is also becoming the defacto for interchange.
