Youtube-dl is an incredible tool, and supports far more than YouTube. I was pleased as punch yesterday to discover that Shoshana Zuboff's talk (shared to HN) on a video site I'd never previously heard of was supported.

There are other related tools.

VLC, both the desktop client (Linux, MacOS, Windows), and to a somewhat lesser extent, the Android client, can also stream video, most certainly from YouTube. Given the superiority of playback controls and for Picture-in-a-picture / pop-up view, this is my preferred option for Android when I want video, generally.

mps-youtube is an absolutely amazeballs console-based YouTube client. It offers search (text, title, channel), playlists, preferred search context (music or all), playback (audio only, video, resolution), and local client(s).

My preferred mode is to curate a playlist off of various searches, and to play that back, either through mps-youtube, or another player capable of using a local file. A disadvantage of mps-youtube is an application-based API cap which doesn't seem to apply to other options.

mpv is a console multimedia player, successor to mplayer, which can integrate with youtube-dl via the '--ytdl' switch. This means you can stream any youtube-dl supported streaming service or target, from raw MP3s or Oggs, to YouTube, Vimeo, and numerous other online media platforms.

I've been making (slightly) increased use of RSS, but have yet to wire that into my media player(s).

All of the console options work in Android under Termux, a Linux-like console userland that's one of the very few things on Android which Does Not Manifestly Suck.
