I took a class on the archaeology of the ancient Near East in college and I remember both the professor and the text book talking about archaeological evidence that might support the exodus - or at least the movement of ancient Israelite people to Israel. But the numbers were in the low thousands, i want to say it was even under 2k. And there wasn't anything remarkable about it. I wish I remember the details, its been over two decades. But basically a couple lines in Egyptian records and then the broader archaeological evidence in the Levant.
