Pretty hard to offer much help as floor plans are highly personal. Suggest you sit in each one and move around some and see which one speaks to you. More importantly spend much time on the physical condition of each unit. Service records if there are any, moldy smells or any evidence whatsoever of water leakage, doe EVERYTHING work as it should and the general cleanliness or upkeep of each unit. Mileage matters only a little (some folks live for many months or years in a unit without driving it much). I suspect the overall choice will be clear to you. You also can hire a professional inspection of condition. Good luck. Don’t hurry.
