A NAS serves data to clients; I know this is tilting conventional wisdom on it’s head but hear me out: go for the most inexpensive, lowest power storge-only-NAS that you can tolerate, and instead…put your money into your data transport (network) and into your clients..
As much as possible, simplify your life - move processing out of middle tiers, into client tiers.
Usually it’s handy to have a display during initial setup and cfg. Also, with x windows port forwarding … you access your server gui over a network like god intended :)
