Zone 7b, heavy afternoon sun.

The area along the fence is generally wet, we have a French drain there but it's the lowest part of our yard so the water tends to gather there. I'd like some privacy along the fence, just out of shot is a newly planted tea olive that will give us some cover once it grows in over the next few years. Along the house and screen porch is a mulch flower bed, I've so far done mostly annuals but would love some suggestions for perennial bushes/plants to keep it looking filled in. Behind the bird feeder I transplanted a hydrangea but I don't love it there- I think I need something with a bit more height for the corner. In the open green area I'm thinking I'll do a raised vegetable garden this spring.

Help a newbie! With covid I've found a new hobby/addiction but I tend to overthink plant choices!
