If you play on PC, PC Game Pass gets you access to hundreds of games but no streaming.
If you play on Xbox, Game Pass Core gets you multiplayer and a few free games but no streaming.
If you want streaming or play on both PC and Xbox, the Ultimate membership gets you everything.
If you want just the PC games and streaming, you can sign up for PC Game Pass and separately for Nvidia Geforce Now, which streams a subset of Game Pass games but at much higher quality and performance.

Thank you to the people who corrected me.
