In Excel, I usually solve

You can autosize multiple columns at the same time by double clicking, just like you do with a single column.
Step 1. Select multiple columns:
Either select all columns by clicking in the arrow in the upper-left corner:
Or click and drag to select a smaller range of columns:
Step 2. Autosize selected columns:
Now double click on the right boundary of any of the selected columns, when your cursor changes to the column-resizing double arrow.
For the keyboard warriors, here's a technique that doesn't require the mouse:
