Its not just storage its also LAN.
Unless you get a board with built in 10gbe, you will need to add that.
Why do content creators need 10gbe?
Because when setup right with a proper NAS, 10gbe can transfer files this fast though your network:
A 10gbe card itself is a 8x pci-e lane device.
Then you got your nVME's, and again... why did you buy a 1600 dollar RTX X090 only to have to be forced to run it at 8x?
But under most cases unless your rendering or folding or crunching, more cores is not always so great at the cost of less pci-e lanes in my book.
If your a newbie content creator, then yeah, you don't need all that stuff, unless you intend to go all in and grow big.
But once you start messing with 20-30min videos which are 20-40gb+ each in size.
Your gonna wish you can move files from NAS to your Content creation box and vice versa at 1GB/s and not 1Gb/s.
