Any tree suitable for hHO is also suitable for OO. Why? Because trees come in a lot of different sizes... :-)
On most layouts I've seen, the trees tend to be on the small side. A mature oak, elm, sycamore, etc, for example, can easily top 40ft - about 5" whether scaled for HO or OO. A mature fir will be 60ft or taller. As for Douglas fir, white pine, etc - think 80 to 120ft. IOW, mature trees should be considerably taller than your buildings. So trees that are in that range or smaller will fit right in. And trees work very nicely to force perspective along the backdrop - just use the smaller ones at the rear.
In addition to the brands mentioned by the OP, there's also Woodland Scenics. But IMO ready made conifers tend too look too toylike, regardless of brand. They need a bit of hacking about. It also helps to thin them out a bit, and glue ground foam leaf material on them - vary the colours a little.
