I want to leave HAOS live and also run docker for an arr stack sparately.

I got a good deal on a pi5 16gb. I wont get another and NUCs are expensive. I want to put an arr stack, deluge and Jellyfin for local single device viewing. I don't see HA using more than 6gb of RAM, or close to it, so tere should be room to manage this.

I have a 256gb sd, I will change eventually to ssd, so I think I have the resources.

I just need the know how, could anyone advise on some walkthroughs that could allow me to not knock HA while I build out the other side.

If you want to keep HAOS as the OS (and the nice update/backup experience), there's a middle option nobody's mentioned yet: run the extra apps as add-ons instead of a separate Docker setup. There are community add-on repositories (alexbelgium's is the big one) that package Sonarr, Radarr, Prowlarr, qBittorrent/Deluge and Jellyfin as HA add-ons, so they live inside the Supervisor's containers and get included in HA backups if you want.

A few caveats for your plan:

  • Do the SSD move first. Torrenting plus a media library on a 256 GB SD card will wear it out and make HA itself slow, and HAOS on a Pi 5 boots fine from NVMe or USB SSD.
  • The Pi 5 dropped the hardware H.264 encoder the Pi 4 had, so Jellyfin transcoding is pure CPU. As iBlessi said, it's fine for direct play to one device; avoid anything that forces a transcode.
  • Keep media on a separate drive or share mounted through HA's Storage settings, so a full HA backup doesn't try to include your library.
