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.
