Framing material in the US is called SPF, which means spruce pine fir. Any of those species may be used and they have similar enough engineering characteristics that they are interchangeable. Occasionally a building will be designed to use a specific species (southern yellow pine etc). But mostly we engineer stick built structures for SPF framing.

    I've been out of homebuilding for a while but we're I was we largely used SYP and our SPF was all pine. Perhaps that was just the region I was in though.

    I was in the rough carpentry game 20+ yrs ago so it’s been a while for me also. For the most part I think if you buy SPF you’re getting some sort of pine species. But it wasn’t super uncommon for us to find a couple dozen fir studs in a bundle.
