What sizes should be in a starter bench chisel set?

Across mainstream reviewers and beginner-focused subreddits, the most-cited essential sizes are 1/4", 1/2", 3/4", and 1". A four-piece set in those widths covers dovetails, mortises, and most general joinery; wider 1-1/4" and 1-1/2" blades are nice for paring but not strictly needed.
