I ended up choosing a design that felt flexible enough for multiple uses, and reviewing
https://www.uspatriotsteel.com/product/20x21-side-entry-carport/ helped confirm that idea. The extra headroom and side access made it easy to roll in vehicles, bring out equipment, or even set up a temporary workbench without feeling like the space was limiting. It’s open, sure, but that openness actually makes it more usable in different ways rather than less.
