LOVE my Synology DS-218+. Any service not covered by Synology's own suite (family and I make use of Synology Moments for photos, Synology Office for docs, Synology Drive for file sync) I have a docker-composed container for. Hardware accelerated decoding on Plex and Synology support (special shout out to my man Lars) is out of this world good.

You pay a little extra up-front but it really is worth it. The box also uses a special BTRFS implementation that is rock solid and easy to manage snapshots for with their own GUI tools.
