Analysis and Post-hoc for Ordinal Variables

#1
My main questions are;
1) For a Chi goodness of fit test, which effect size do you use? I am being told Cramer's V, Phi, Omega and W!
(There seem to be a lot more answers for a Chi association test, but not for a Chi goodness of fit)

2) Can you use an Odds Ratio with a Chi goodness of fit test? If yes, what would this tell us? Perhaps the odds of "y" happening rather than "x"/the control?

3) I am also running several Fisher's Exact Test for 2x2 contingency tables with small values.
I would love to use some post-hoc analysis or even a measure of effect size/odds to make my results more interesting than a simple Fisher's significance test-- but I have no idea what I can use.
