From my own experiences as a T shaped person, I'd say that's you, or you're well on your way to it. Job and life transitions aren't always so smooth as that T develops, but it's those occasional bigger shifts that help broaden the experience you have.
It's not always easy being T shaped, as you kind of have to start off as a minus sign (short horizontal) and move towards being more of an em dash as that vertical line begins to emerge. You can feel scattered and unfocused, but at some point you see the breadth of your experience you've gained, and that you're capable of learning new things.
An approach perhaps to jobs is not to say, "I have done these many things - perhaps one is something you want?" But instead say, "I have done many things, and that shows my curiosity, interest in learning new things, and flexibility." Heck, even a job at Taco Bell makes that T even more interesting, even if it's not a big career highlight.
Irrespective, the next phase doesn't have to be the destination - sometimes it's just another step in the journey. And don't apologize for your diversity, but see it as a strength. Some day you might find that employer that says, "Oh actually that's exactly why we hired you!"
