I think the 870 has been dismissed as an option too quickly. I have a 1968, 20ga. Wingmaster and a 2013, 20ga. Youth 870. Both guns have been hunted, both have been soaking wet, both have been snowed-on, both have shot lots of trap with zero issues with shells sticking, or getting jammed in the chamber. Even Winchester white-box grade. My nephew bought the 12ga. Express combo a few years ago and has hunted turkey, deer, and grouse with it and in spite of how badly he neglects this gun, it still functions great. (save for one batch of Winchester target loads, one time) Not saying DO get an 870 of DON'T get one, just seems like the advice is pretty lopsided. As for the 3" vs. 3.5"~I'm 6'1", 300lbs., and not overly recoil shy...but I take no pleasure in shooting 3.5" shells from a pump. Your shoulder eats all that recoil and I'd argue that it isn't needed for the things you say you want to hunt. High-flying geese maybe...?
