The “auto-fit” is a value of the repeat() function used in grid-template-columns/rows and it is supported in Webflow. I was just focused on a property, not a value of a function and look at that function as auto placement. Chalk it up to late nights. Note: Auto-fit can’t be enabled when there are auto, flexible (FR), minmax(auto,auto), or other auto-fit columns or rows.
Here is a video on how to set it on a column.
