Tikka makes or has made, variations of their T3X with 16-20" barrels, with and without iron sites. Without a caliber debate, some calibers, like 308, give up little from a short tube. Others like 243, do so there is some consideration to length, based on caliber. The longest barrel i want for a bolt action, is 20" regardless of caliber. However, for cartridges such as 308, 358, etc. 16" is more than sufficient. Out of the box, a Tikka Ranch rifle ticks all the boxes. Optics, to me are more important than the nuances of a 20" vs 16". For what you describe, i would want something with illumination, to be able to pick my crosshairs out against the brush and deer in those conditions.
For what it is worth, my woods rifle mirrors Kamlooky. A single shot CVA. Light and handy as hell. No real penalty in the woods either. If you miss, you aren't getting a follow up, and if you need to put a wounded animal down, you can reload quickly enough.
