We ran into the same problem and ended up splitting things by how often we needed access. Yard tools, lawn equipment, and seasonal stuff all went into a shed, which freed up a lot of space in the garage. The garage stayed focused on the car and a small workbench. When we were planning it out, I looked at layouts like https://www.storageshedsandgarages.com/product/single-car-gambrel-garage/ to understand how much vertical space a garage really needs, and that helped decide what didn’t belong there. Anything bulky but rarely used usually makes more sense outside the garage.
