Touchofgrey, whenever there's various eyewitness, there will invariably be differences and contradictions. No two people see the same event in the same way. So the few contradictions are easily explained by differences in background, personality, circumstance, writing style and time passed since it was documented.
Albert Huck's "Synopsis of the First Three Gospels with the addition of the Johannine Parallels," edited by Heinrich Greeven, is a valuable resource for study in this regard. I have the 13th edition. As far as I can remember, Kurt Aland also published a synopsis of the four gospels. There are differences, and that is to be expected.
E.g., "in the healing of the blind man (men?) near Jericho, Luke states it took place as Jesus “drew near to Jericho” (Luke 18:35). Matthew attests it happened after Jesus leaves Jericho and there were two blind men healed (Matt. 9:27). Mark narrates both the entrance and exit of Jesus from Jericho; and while leaving Jesus encounters and heals blind Bartimaeus (Mark 10:46)." Questions that come up: How many blind men did Jesus heal on that day? Was he coming or going or both? Did the writer(s) witness the occasion or was it narrated to them?
