Maybe Kodi, you can customize skin so it shows only library you created, has lots of skins, can look pretty,.. It can scrape all the info from imdb or similar sites, so every movie can have cover art, description, rating,.. Once created library can be browsed by looking on cover art pictures listed by name, year, rating, director, genre,.. supports continuing where you previously left, bookmarks, can automatically hide already watched content,.. etc it has extensive plugin support, lots of official and unofficial addons for streaming stuff, trailers, audio, youtube, twitch, vimeo, program addons even some rom games addons,.. can be complicated or simple as you want,.. but for this use case you won't need any plugins, maybe a different skin, something your daughter would like. lots of tutorials on kodi wiki, forums and youtube works on all platforms, free and open source
