What are some common sarcastic words and phrases to avoid?

This is at first sight off topic because it seems to depend on opinion. Answers to most of these examples depend on context, tone of voice or opinion. If they are delivered with a warm smile in circumstances where your approval may reasonably be expected they are acceptable. If they are delivered with a withering and offhand sneer they will offend.

Your list could be extended ad nauseam: “Yeah, right”, ”That worked well” ...

Nevertheless, one phrase stands out as an example of intrinsically sarcastic usage rather than a matter of opinion. “if you say so” is almost guaranteed to offend because it says that the speaker (only) agrees with you because you have spoken. Had you not spoken they would not have been of the same opinion (so they are passively or dismissively disagreeing with you) or they would not have considered the matter (so they consider the matter, and your opinion, trivial). Either case offends.
