What are the differences between oil-based and water-based polyurethane finishes and which one would be more suitable for my project?

Oil-based polyurethane finishes are more durable and provide a richer color, but they take longer to dry and have a stronger odor. Water-based polyurethane finishes dry faster, have a milder odor, and are easier to clean up.

For your project, consider using oil-based polyurethane if you prioritize durability and color richness, and are willing to wait for longer drying times. Water-based polyurethane may be more suitable if you prefer a faster drying time, easier cleanup, and a milder odor.
