Hmmm, do you actually have 10uF 0603 ceramic caps in hand?  I'd bet
dollars to doughnuts that you either haven't looked for them, or your
haven't ordered them yet (so you haven't found out that they are only
brochureware).

The reason I say that is that you can't get 10uF 0603 ceramic caps
. . . to the best of  my knowledge that is.  The 0603 package is too
small to support 10uF.  Getting 10uF into 1206 is pushing it.

I'm willing to be proven wrong, of course, but you should at least be
aware that 10uF in a 0603 package is a stretch.  You're better off
with Ta caps when you get to these larger values since your options
for procuring real parts are much better.
