The usual B&W films are color balanced for tungsten but

muting the preponderant available blue. Would an orange
filter be more correct? Also, yellow or orange, would
filter factors need to be increased in such a blue

Consider the chance you are thinking this out waaaay too much. Sure, thought is good in general, but there's a time and place, and it aint now.
Just go shoot "the forest floor" and see what you get. If you are shooting flowers or something with a strong color, against a contrasting colored background, filtration will be useful for special effect, but the forest is bland color wise, and generally will not respond usefully to any color balance corrections you may impose, other than to make your exposures longer.
Forest light never stopped Wynn Bullock, A.A., Weston and co, and they all got amazing images without worry about the exact spectrum of the forest light. Heck, you can get pretty far with color film in the woods without elaborate color correction. Maybe a uv/sky filter or a modest warming filter would be fine.
Had you a very accurate color meter system, I'm sure you could discern some sort of very modest slant to the spectrum at the forest floor, but with any BW film having a fair claim to being panchromatic, there will be no show stoppers whatsoever if you shoot with no filtration.
The worst issue is likely to be contrast if the day is sunny, since any patches of direct sun will be far above the predominant brightness. I love gray days.
