My layout benchwork is similar to a deck layout
I used;
2X4 standard grade (not the cheapest) for legs and cross pieces
1/2 plywood for top sanded one side Not particle board because I don’t like particle board dust and not hardwood covered for cost reduction and cause it’s covered anyway
Have also used steel 2x4s made for framing in past for longer runs, over 8 ft
Pros; Cheap, easy to design multiple sizes, readily available sturdy and easily covered with homasote or pink board
Cons; Have to cut, heavy(relatively), hard to make pretty outside curves,maybe harder to transport
Your 4x12 ft will layout well off 4x8 sheets
Hope this helps
