>We also know for example that the types of beliefs detailed in Exodus, especially the idea that the Israelites worshiped Yahweh alone as the only God, are not historical. Belief and worship of other gods were common in both the ancient kingdoms of Israel and Judah long after the supposed time that the Exodus happened - in particular El (who was later associated with Yahweh) and Asherah (who was sometimes seen as the wife of Yahweh). So at least this aspect of the Exodus narrative is directly contradicted by archaeological evidence.

I feel like you haven't read Exodus because it describes in detail the early Israelites' predilection for idolatry.

The book of Joshua details the supposed conquest of Canaan by the Israelites, which archaeological evidence rather disfavors--there's no discontinuous horizon in cultural adaptation between the supposed Philistines and the Hebrews following Jewish dietary laws, for example, and the settlement sites just are not inhabited during the time period that they were supposedly conquested.

Calling it idolatry is ahistorical though. Worshipping yhwh alone came much later.
