I don't use OMV, but I have a nas server I built and here is my .02
- set up an smb share in OMV for windows. Mounting that in windows should be trivial (don't hold me. Haven't used windows in years now, but last I used win10 smb was super easy to mount)
- look into docker on OMV for deploying stuff. I run docker on my NAS and host a bunch of stuff including:
- jellyfin for all the rips of my DVDs
- navidrome for all the rips of my CDs
- nextcloud to replace google stuff
- radicale for my calendars
- Joplin server for my notes
- mealie for recipes
- more stuff I can't think of right now
- with docker, if you want a GUI for creating, managing and interacting with your stuff, look at Dockge and Portainer
Edit: added more stuff
