Is it good practice to let your Wort cool overnight, then pitch your yeast in the morning. I have heard, there are 2 schools of thought that might affect the taste of the beer. Also, could contaminate the beer.

If your sanitation practices are solid and you do not leave the wort uncovered overnight, you should not have a contamination issue.
Regarding the effect of delayed pitch, there is a homebrew scale experiment: http://brulosophy.com/2019/01/07/the-impact-of-delaying-yeast-pitch-exbeeriment-results. While obviously the sample size is small, the data seems to indicate that if not for contamination, you should not have a real difference in taste.
