I have it turned on and set to “medium.” I have the remote in a case that makes it thicker and heavier in my hand. I find that make it easier to use as well. YMMV

Battery capacity really doesn't have much to do with battery usage. Just how much the battery can hold compared to when it was new. I used to have a Series 4 with 83% capacity and it would last me 20 hours on WatchOS 10. I upgraded to a Series 9 and gave the 4 to my spouse. It might last them 12 hours but they have a lot more notifications activated on it and use it for Siri extensively.
Your usage, notifications, and background apps installed are what eat your battery. Unfortunately, the watch doesn't seem to report the apps using the most power like other devices. This means you have to use trial and error to try and reduce usage the most.
Profit Margin. Less packaging cost, more units per shipment, fewer cables to manufacture while prices remain the same or increase.
My spouse and I use the app OurGroceries. It has a complication for the watch face. Tap it and we get our shopping lists. Our lists are organized by store like Costco, Target, Supermarket, PetSmart, etc… each list is then organized by category.
