That's really good gear list for a first timer, and I've agreed with every rec so far. Here's my partially redundant opinion.
Ditch the rain cover. They are loud, heavy, and don't work terribly well. A contractor bag or 55 gallon drum liner can protect everything in your pack in a downpour, and be used as an emergency shelter or cut open to give you a tarp to butcher game on.
Carry the extra socks. Socks are the absolute silliest place to try to save weight. I obsess over socks and sock changes, and will swap through three pairs a day. It's good to have all your socks be the same make and model and to test them beforehand, so there's no surprises about boot fitment.
It says filter straw in your pack list. Are you referring to a lifestraws? Lifestraws are awful, if you want to carry a filter spend the $20 - $30 on a Sawyer squeeze.
I go back and forth on steripens, the adventurer model I've had for a decade is very convenient and great in high alpine stuff. It is also super finicky in cold, and won't interface with a smartwater bottle so I have to carry a heavier nalgene. I usually leave my steripens at home because I filter all water anyway. Because sterilized frog sperm is still frog sperm.
Bring more duct tape than you think you will need, I like it for covering hot spots on my feet and think it works better than any medical product. You could wrap some extra around that smart water bottle.
I always carry soap. An ounce or two of Dr. Bronners in a sample sized dish soap container is great insurance against ending a hunt early due to something embarrassing. Being able to actually wash your hands and other critical bits is crucial. You don't want to have to explain to friends and family that your hunt ended early because you got giardia symptoms from cooking with poop hands, or debilitating folliculitis from general swamp ass.
Finally I would suggest you assess your tent, pack, and sleep system going forward. Those three items together are 14 lbs on your back if I'm reading the chart correctly. Upgrading any one of those would save the weight of all the other gear discussed so far. If you get more into mountain hunting, think of new gear in terms of cost per ounce saved. Ignore the siren song of some $50 titanium doodad that will save you an ounce when a $500 sleeping bag upgrade could save you 24 ounces.
