Hi Schill,
I think you've gotten some great advice so far. IMO, I find quilts with simple piecing are great with lots of fabrics, but with more complex piecing, fewer fabrics are nicer. Of course, there are definitely exceptions to that generality.
I will say, if you have 2000 yards of fabrics, you have lots of leeway to experiment and find out what you like. That's enough fabric for 200 queen-size quilts! You can sew for the next decade without having to purchase much.
I suspect you will find that it's not the number of fabrics that matters; it's how they play together that makes a quilt a success (or a disappointment). It's taken me years to get "good" at selecting fabrics and getting the look I want in the end. If you want to branch out from precuts, the only way to do it is to actually make quilts and see how they turn out. Have fun!
