accessing my Ultimate Game Pass

But my subscription is for Game Pass Ultimate and not for Game Pass for PC... My family should have access to the games, right? Otherwise, what is the family plan for?

Do you have Game Pass or Game Pass Ultimate? You need Ultimate to access EA Play for free on the console.

If you only have standard Game Pass, not Game Pass Ultimate, then you'd only be able to access Game Pass games that are available on the console. A few of those games are Play Anywhere and you may be able to access them on PC, but you'd need Game Pass Ultimate if you want both Game Pass for console and PC Game Pass or to use cloud gaming.

Are you absolutely sure it's Game Pass Ultimate? Because there are 3 versions of Game Pass, the console version, PC version and Ultimate, which is the merger of Live Gold with Game Pass and also has Game Pass access on the PC.

It depends on what you bought. There's Game Pass for Console, Game Pass for PC, and Game Pass Ultimate.

If you only bought Game Pass for console, then it won't work on a PC.

Game Pass Ultimate includes both version of Game Pass plus a Gold subscription. So if you bought Game Pass Ultimate, you should have access in both places.
