First there is unloaded Q, for most iron powder toroids with a single layer winding
a good working value is 200. It can be higher, I've see 275.  Its not all that critical.
Test for various values and you will see.

Loaded Q is a internal design feature and hard to bound and interacts with the
filter equations.  Easy answer you don't get to choose.

There is a yabut... and untested in that example.  Assume correct +-5% on
inductors and go +- 10% on caps.  Then play with the Q of caps as the possible
range is 500 to 3000.   Unlike the inductor you do get to pick higher Q over lower.
