Realistically, any LTS distro from a netinstaller or minimal image that can use a kiosk compositor like cage. So, the usual suspects of Debian, OpenSUSE, AlmaLinux, RockyLinux (or a derivative of one if the native distro doesn’t support Raspberry Pi). Then you just have cage open the browser of choice on startup (e.g. chromium --kiosk <url>) and you have a lightweight and relatively secure web kiosk.

Nvidia 9, 10-series support is quite poor. Your experience at best will still be worse than AMD, Intel, or more modern Nvidia cards running the nvidia-open kernel modules with the latest Nvidia drivers.

You’re likely looking for this docs section for Caddy. The failure is the automated request to populate Caddy’s root CA cert to the host system, but obviously failed as it doesn’t have root permissions. As the docs state, if you intend to use the local HTTPS functionality of Caddy, you can manually run caddy trust privileged in order to populate the Caddy root CA cert manually. If you intend to disable the local HTTPS functionality (such as if you’re running Caddy behind a http reverse proxy), you can ignore the mail message.
