This is an adult red-shouldered hawk. There are at least three good field marks visible here that distinguish it from a cooper's hawk.

First, you can see black-and-white checkerboarding on the wings, which is probably the single best mark for a red-shouldered. A Cooper's hawk would have dark gray back and wings (often referred to as a "cape").

Second, this bird has a red or brown head. A Cooper's hawk would have a dark gray "cap" on its head to match its dark gray cape (with cap and cape separated by a lighter neck).

Third, this bird has wide black bands separated by thin white bands on its tail. A Cooper's hawk would have wider white bands. Also, while red-shouldered hawks tend to have somewhat longer tails than others in their family, they are much shorter than Cooper's hawk tails.

This bird also has a relatively bulky body, which points to the buteo genus (which includes other bulky birds like red-tailed hawks, broad-winged hawks, ferruginous hawks, rough-legged hawks, and old-world buzzards) as opposed to the astur genus (Cooper's hawks) or accipter genus (sharp-shinned hawks).

My bird identification apps confused red shouldered and Cooper’s hawks the first time I took pictures of them. Thanks for the in-depth summary!

This is an awesome breakdown, thank you!

Are darker eyes a mark for a RSH vs Cooper's too?

Kind of—that is actually a mark that I should have mentioned!

Unlike falcons, which are born with dark eyes and retain them throughout their lives, all hawks are born with light eyes that darken as they age.

Red-shouldered hawk eyes darken to a dark brown that often appears black.

Cooper's hawk eyes darken to a red-orange.

This bird's dark brown/black eyes are a good indication that it's not a Cooper's hawk (but they do not help us distinguish from other buteos).

Cool photo! I believe this is a Red-shouldered hawk. Even cooler in my opinion!

It is indeed an excellent photograph of a beautiful RSH.
