1) No detachable magazine for the same reason. I had one fall out of my 760 pump and it cost me a bull moose.
2) I prefer wood. Battle scars add character. If it bothers me, I will refinish the stock.
3) Definitely do not like muzzle brakes or suppressors. I shot a couple of animals long range with my PH's suppressed 270 WSM and it was a delight to shoot. Fortunately, he was carrying it not me. If I was a range junky, I might feel differently about suppressors. But for the little time I spend shooting paper it's just not necessary.
4) I prefer rifles and shotguns with some weight to them. Heavier rifle mitigates recoil. Heavier shotgun swings better. To me balance is most important and I have found very few lightweight long guns that balanced well. I carry this heavyweight old Browning humpback all day, day after day, every fall for six weeks hunting uplands. Unless the bag limit is filled, it's in my hands with sling detached. I can take it and I'm no body builder. Works for me. I miss very few birds or clays: my skeet average is 22/25 ... and I'm half blind (literally!). Loaded with three twelve gauge shells, 31" barrel, and dressed in plastic it weighs just a bit over ten pounds.

My 30-06 1903A3 weighs slightly more when fully loaded with six rounds. I can carry it all day no problem. And in rough country.

My 404J is a bruiser at over eleven pounds fully loaded with four rounds. I carried it all day for several days hunting buffalo in 2023. Yes, I notice the weight but my fragile retinas need it for recoil mitigation.

All guns are balanced perfectly at the forward half of floorplate (or just ahead of magazine loading port for A5). Balance is more important than gross weight.
5) Classic styling is not terribly important to me. Because I stalk big game up close and I'm often shooting moving targets, quick acquisition is more important than cosmetics. Monte Carlo cheekpiece is fine for getting me on the crosshairs in a hurry. Low European style comb not so much. Fit is paramount, especially for a quick shooter. My shotgun wears a slip-on recoil pad for extra LOP when shooting in shirt sleeves but it gets pulled off on extra cold days when I'm layered up. Not pretty but it works.
6) I agree about minimizing attachments. Tried a bipod for a while. Didn't work out. Throws off gun's balance and rarely practical. I do have quick detach rings and iron sights on both rifles. Good to have another option for adverse conditions or scope goes south. Again, maybe not the prettiest setup but it works. No lighted reticles. Just something to go wrong. I don't own a range finder or chronograph but contemplating buying the latter. I do reload.
7) I'm not into long range shooting, either at targets or animals. Sub MOA is overkill in my book. MOA is good enough for shooting big game out to 200 yards. Sub MOA for a dangerous game rifle is just silly.
Keep it simple. Don't overthink. Choose what works not what is trendy.
