Cloudflared tunnels are for very niche use cases like accessing a container or VM. They state no bulk file transfers or any kind of long term, high bandwidth use cases. So it depends on how hi-fi your music streaming is, but definitely not for movies or tv show streaming. If you want to do high bandwidth stuff, setup a wireguard VPN.

Streaming through a CF Tunnel is a quick way to get a one way ticket on the Cloud Ban. They strictly and largely state that CF tunnels are not to be used for high bandwidth use cases like streaming. Not to mention, setting up a CF tunnel is literally a one liner in the TrueNAS shell or a click on the CF'd apps installer and pasting a token. The rest like subdomain, IDPs, etc is all managed through Cloudflare and not touchable through Hex OS unless Hex could use the CF api, which IMO is a waste of time. Homelabs being hooked up to public domains can be dangerous if you dont know what you're doing, and we can only expect so much from HexOS developers. At some point, people need to learn a thing or two about safety/security and realize not everything can become a one-stop-shop.

What you are referring to and calling "cache" are likely SLOG, L2ARC. The problem is, unless you are running 64+GB of ram, you will not see any appreciable performance gains from using those functionalities. You will be much better off investing in RAM on the server as TrueNAS ZFS uses RAM for caching anyway and is a much more effective solution. What you are seeking is more a function of Unraid and while you can set up SSD "caching" as a new dev in TrueNAS, you would have been better off investing in RAM than a cache SSD.
