Coyote hunting scopes are a very personal thing. I call coyotes in the west and find a 1-4x20mm scope perfect for my combo guns and 1.5-6x4?mm scopes on my bolt and AR. I do have a compact 2-7 on a little Sako 222 and a couple of 2-10x4?mm on 22-250's but have never taken them off 2x to kill coyotes. I tried a 3-9 and found it didn't have enough FOV for the way I hunt
Lighted reticles I like, early morning, late afternoons, cloudy days an illuminated dot really stands out in forested or brush country, duplexes can get lost in the branches when trying to track a coyote trough the branches.
Interestingly a fellow that hunts the same country I do uses a 6.5-20x??mm but he tends to set up on hillsides an call big open flats and I head down in the bottoms and thicker brush. I've always found it is easier to call a coyote in cover than to try and call him out of it. The second thing I've found is if the coyote is far enough away to need the top x's on the scope there is plenty of time to turn it up, if they are coming in close enough to need the lower X's/larger FOV on the scope there is never enough time to turn it down.

Over the years I've posted pics of coyotes and my combo guns with with the 1-4's on them. So ask if you want to see them.
All but one of the pics shown are from this past season, I was experimenting with cartridges this year and left the 22-204 home.
One of my favorite types of terrain, mesquite covered sand hills, most shots are 10 to 70 yards but can stretch out to a couple hundred if you catch one on a side ridge. This is great country for the combo guns, I'm too old to be packing a separate rifle and shotgun.
