If you shop at Home Depot or Lowes the only cut you'll find are from flat sawn logs.[1] Even at lumber yards most will be cut this way.<p>Because I don't have a planer, and don't want to spend megabucks on furniture-grade hardwood for my learner projects, I have to spend a considerable amount of time picking through pieces, whether dimensional construction lumber or squared project pieces, checking the grain to find those pieces cut near the middle, but not directly through the core. And then of course checking that it's not otherwise too warped or twisted. See<p><pre><code> https://wortheffort.com/wordpress/archives/142

I think the only places you'll find lumber cut using those other patterns are lumber yards selling high quality lumber for furniture or architectural pieces, often sourcing from boutique mills. Or places selling reclaimed lumber from the days when lumber was harvested from old growth forests and it was cost effective to setup a large mill using different patterns. The trees from modern farms don't get big enough to use the other patterns; at scale the only cost effective method is flat sawn and letting downstream purchasers sort through the mess.<p>[1] The exception may be the poplar and oak project boards, but they're so expensive at the big box stores I don't even bother looking. I think poplar is pretty stable so they're probably flat sawn, too.
