I think I can create a CNAME record for *.media to point to the Tailscale address of the reverse proxy
This approach, but if you setup your server to advertise subnets you can use your local IP range instead of tailscale's. Port numbers for individual services would be handled by your reverse proxy, you can setup a subdomain route for each service.
Instead of having to keep track of bookmarks you can use something like homepage on the root of your domain, as a dashboard to navigate to all other services.
My setup just has the local IP (of the reverse proxy) in the domain's DNS records, and I have Tailscale on my home server setup to advertise subnet routes, so I can use the same local IP when at home or remote via Tailscale. No need to use your public IP or open ports or anything.
Irfanview has been my image viewer on Windows for years now. You can install the full plugin pack from the main website (button below the main installer download) and you'll be set for just about anything that identifies as an image.
If you're ok with doing some selfhosting, a DNS filter like PiHole or Adguard Home should take care of those. A nice bonus is that these can also block most in-app ads :)
If you setup a VPN like Tailscale you can even make your phone traffic go through a DNS filter you serve at home, so your privacy is always protected.
It looks like the dev is working on porting Tasks to other platforms, including desktop. Though it's still in development, so not a solution right now.
It works just fine actually, the full (non-lite) version. For how long is still a question but the Vivaldi devs are keeping manifest v2 support alive for now.
For the CPU: I have a AMD Ryzen 5 8600G in my TrueNAS Scale box, I use the integrated graphics for hardware transcoding in Jellyfin. If you don't need transcoding it's probably overkill.
For TrueNAS you'll also want a lot of RAM, as ZFS (the filesystem) gets faster with more ram by using it as a cache. My box has 32 GB, but 16 GB should also work, especially if you're going with SSD storage.
And don't go cheap on the power supply, get an efficient one from a good brand (I prefer BeQuiet).
