, nice to meet you!
You indicated that you wanted broad leaved, evergreen flowering sbrubs.
Though I'm in California now, I lived in the Cleveland area for many years before coming here. Our climate in Ohio is similar to yours, though, thankfully, we don't get nor'easters . . . .
I concur with everything @lenaitch
said, and add:
You already have what looks like two rhododendrons. Those are really pretty when they bloom; they're a bit fussy about soil, but it appears that you have already met the conditions. "Rhodies" come in a variety of colors, and white, as well as combinations. I suspect that your blooming season is either here or coming up soon. If that's the case you might want to get a couple more Rhodies.
Hydrangeas bloom later in the warm season, and they have pretty broad leaves, and some turn a bright blue in acid soil, which you have, because Rhodies have to have acid soil, too.
Those are pictured below. Even when not blooming the plant has a lush, leafy look, though it's deciduous.
If you have to have evergreen, but don't want more Rhodies, maybe consider "Andromeda" or "Lily of the Valley" shrub. They're evergreen, and in addition to the flowers, they have pretty new leaves in spring, and berries in the fall.
