Using ACF?
Create two group fields, one for the left column and one for the right and set the width % of each field.
Inside these groups add a fields and or sub groups and fields. For example the left column would have a “Product Information” group and the right would have a “Pricing” group and an “Organization” group.
Then you would add your fields to one of these sub groups setting the width % as needed for each field.
Looking at your image you would set the display of each group/sub group as block.
Add a healthy dash of custom CSS and possibly a cup of custom JS. There are thing in that form that cannot be achieved with ACF alone.
