I personally was thinking a 2.5-20 nx8 myself, or mid range athlon like a Helos btr gen 2 2-12x42. But if you wanted to blow some more coin on a higher tier, you could do the 4-16 atacr, or the 3-12x50 zenith from S&B. Also depends on what you want your overall weight to be as well. Most guys like a lightweight rifle, with a bigger obj for a tad more light gathering but it's all personal dependance.
I personally dont need 2000 dollar glass quality or light gathering capabilities because I just dont feel comfortable taking shots at dawn or dusk anyhow, nor do I need a light weight rifle; carrying a heavy rifle doesnt bother me. I prefer small, lightweight optics because I dont like unwieldy rifles, or top heavy setups. I like them to be a little more balanced.
Also, it kind of depends on the type of rifle and the type of hunting. Utilitarian, rough and tumble hunting, I wouldnt get any nice, nor new, I'd buy 2nd hand, If it's the hunt to maybe get a deer, maybe not, but more for guys getting out of the house together and show off their high end Steyrs or Sauers with old classic kahles or hensoldt scopes, then I'd pick something expensive and foreign lol. Hey, it's a thing.
