As a TV centric distro, there is libreelec libreelec.tv You can use it to stream media from jellyfin, plex or other streaming platforms with plugins

It runs kodi that you can also use in other distros as a package

Kodi supports hdmi-cec, which allows to use your TV remote to control kodi, the hardware needs to be compatible too though (raspberry pis are compatible) There is also a mobile app, Kore, to control kodi on local network

The UX may not be as slick as androidtv/appletv but it is customizable
