There were a number of Semitic tribes in Canaan going back before the time of Abraham, but the Philistines weren't among them. They were new arrivals of archaic Greek origin, probably remnants from the Late Bronze Age Collapse. They were Indo-Europeans aka Europeans, not Semitic.
The Canaanites became known in history as the Phoenicians, who eventually founded Carthage and became the feared enemies of Rome. Other major Phoenician cities include Tyre and Sidon.

Modern day "Palestinians" are just Arabs.
