Softwood, Hardwood, Dry wood, and Dark wood can spawn from any tree. The drop type is dependent on the biome the tree is placed in, not the tree’s style. These are topiaries from the plaza placed in the Forgotten Lands. A bonus tip is to pave the area around the tree which will make it easier to spot the wood.

We do not have a respawn timer on the wood just yet, though Softwood is known to respawn within 5 minutes while the other three wood types taking a lot longer & drop a lot less. So if you need more of a specific type, you can create a “tree farm” but you need to make sure they are spread up in a pretty good distance.
Wood Spawn Pool
There is one spawn pool for wood in each biome. If you need hardwood you are also dealing with other types of wood that also spawn in that biome.
Whenever there is a random pool of potential choices the best strategy is to pick up/clear out all spawns from that pool to maximize your chances that what spawns next will be the kind you need.
We have no data on percentage of soft vs hard (or dry or dark) wood in any biome. But if you only pick up hardwood and leave the softwood (or other wood types), each new piece of wood that spawns can still be any type that spawns in that biome. Therefore you are gradually eliminating any spawns of hardwood if you only pick up hardwood.
