I wouldn’t recommend running container volumes over network shares mainly because network instability between NAS and server can cause some really weird issues. Imagine an application having its files ripped from underneath them while they’re running.
I would suggest containers + volumes together on the server, and stuff that’s just pure data on the NAS. So for example, if you were to run a Jellyfin media server, the docker container and its volumes will be on the server, but the video and audio files will be stored on the NAS and accessed via a network share mount.
