They should all work fine. The tolerance and temperature coefficient will be factors in determining the price but not the frequency of oscillation, the tolerance of the crystal will be much more of a factor (not to mention luck in picking a good one). A while back I suggested trying to fit a tiny trimmer cap in place of one of the fixed caps to allow you to adjust the frequency, but I haven't gotten around to experimenting with that.

I noticed one can get several different type capacitors ie ceramic, thin film, etc in 0603 SMD with different tolerances 5%, 3% or 2%. Would anything work, or one better than the other for this application? Any suggestions.
From a temperature/environmental stability perspective: polystyrene dielectric if you can still find them. Outside of military/esoteric
capacitors they were the choice for timing critical applications.
Unfortunately they are only available in leaded packages, though
quite minuscule and inexpensive at the values required here.
Failing that an NPO/COG ceramic.
But yes, this will address drift only and you'll need to compensate
the xtal to the intended frequency if that's needed.
Another thought is to forego absolute accuracy of the xtal oscillator in favor of stability, and compensate for whatever
off-target frequency exists numerically.
