Had a calcium score, coronary cta & stress test bc of caroited artery bruit & chest pains... All norm! Is it safe to say the bruit/pain is benign?

Yes. Sounds as though your carotid has no significant plaque or anatomic cause for your murmur. Therefore benign. Same for your chest pain if est normal.
Results... If cta, cardiac stress, and calcium score are negative, that is good news for the heart and coronary arteries. As far as the bruit..... Did you have a carotid doppler / ultrasound? Usually this will tell the percent blockage in the carotid which is likely causing the bruit.
