Another vote for the Exo K4 5000.
I have it and love it, it’s big enough for any hunt or camping/hiking I plan on doing, and will compress down small enough for daypack use as well and not feel sloppy.
As others on here will recommend, go try any and all frames on you can, to see which one fits you best. What frame fits me and feels good to me, might not fit you the same. And all of the big 3 frames will also handle the weight well, but it all boils down to fitment to you.
For actual pack size, I would stay in the 5000 range, it’ll allow you to pack everything you need while keeping you from packing a lot of fears as well. Each of the big 3 (Exo, SG and Kifaru) all have packs in that range.
Good luck with your search for a new pack, check classifieds as there is always the big 3 on there, then you can get a high end pack at a more budget friendly price.
