Must agree with branson4020, however being organized for how you work is next best. I don't do much mechanical or project work in my garage, have a basement workshop.
These photos show 3 sides or our garage - 2-car. A cabinet for small items to always be handy. Slatwall for hanging, shelving for larger seasonal items and storage tubs plus a stand-alone shelving unit. The shelving unit is on casters and behind is a "sleeve" where storm door inserts are kept. Floor space can quickly be vacated for cleaning.

Tool rack. For me, not a fan to bulkier head hung low.
