The best layout is not a decorative diagram copied from someone else's climate. It is a spacing and access plan built around the mature plants you actually intend to grow.
Put tall plants where they won't shade smaller ones
Use expected mature height and the path of the sun to prevent accidental shading.
Group by irrigation needs
Keep dry-loving plants away from areas that must stay more consistently moist.
Give perennials permanent positions
Reserve stable spots for plants that will remain for multiple seasons, and use flexible gaps for annuals or biennials.
Keep a harvesting lane
Paths are functional infrastructure. Make it easy to inspect and harvest plants without stepping into root zones.
