Why 8 TB is a sweet spot
8 TB sits where price per terabyte is keen and the drives are quiet, mainstream and widely stocked. Four 8 TB drives in a four-bay NAS give roughly 21.8 TiB usable in SHR or RAID 5, enough for a large media library and backups in most homes, at a total drive cost that stays reasonable. It is the capacity we default the calculators to for exactly that reason.
If you expect to outgrow it, note that fewer larger drives (say 16 TB) reach the same capacity in two bays, leaving room to expand and drawing less power. The drive-count calculator shows the trade.
Which 8 TB drive to buy
All the mainstream 8 TB NAS drives are CMR, so the choice is price and noise. IronWolf, Red Plus and N300 trade the top of the CA$/TB table between them; an 8 TB Exos sometimes undercuts them all if you can accept the noise. Buy whichever is cheapest per TB in the table below: they are all safe NAS drives.

Kept out of the table above: a renewed or used drive has a different warranty and an unknown history, so its price per TB is not comparable with a new drive’s. Each row shows its condition.
