cannot decide on a home use nas

[Enquiries]

i have watched many of your videos but still cannot decide on the nas for me
and in the past i had a western digital my cloud 4tb nas
this met all my needs in a single disc config until wd made the product end of life
on new device i will place all file types on new nas as before
but this time round i want to take cine films and digitise them and also my dv videos from holidays on video camera
i would edit on laptop and copy finished video to nas, not edit from nas
after i have them as digital video files (not 4k) i want to place them on nas to watch on my phone or smart tv
i would also like to share the films out via a shortcut to my family
so they can access my nas on their smart tv and play movies they may be in from 40yrs ago
i could do this in past with wd my cloud
i have shortlisted to qnap ts-233 or synology models ds218,ds218 play,ds220+,ds220J
but i do not want to pick a device that may be end of life soon on error
was going to add seagate ironwolf 4tb disk (x2)

DS220+ still has around 8 years left for the software updates. Synology usually support their NAS for 10 years.
The latest model is ds923+, but it will only stream 4k locally. Remote access is limited to 1080p. DS220+ can do 4k remotely.

I hope this helps.
