Plenty of people still call them pole barns, and they are still state-of-the-art for cheap shops/garages. When people are thinking more "value" than "cheap" (same thing, but sounds nicer), then you might call it post-frame building. Poles or lumber for the posts, lumber to span between posts, sheet metal on outside. Lumber trusses and metal sheeting for roof generally.
Timber-frame would be a similar but different thing.
I could type more on the subject if you are interested in one for a specific purpose. Residential for example you might find inspiration in terms like shopdos (shop-condo) or shouse (shop-house).
Check out RR Buildings channel on YouTube for high-end builds, for shops or residential.
