Your colour looks more like a 22R to me, but that might just be my monitor.
So send a sample in of the front of your hair to get the best match.
The area you're replacing is from the lighter area of your hair, so thats what you want to match.
As you say, you have plenty of hair everywhere but where its receded from.
The texture of your hair is quite fine and another reason to send in a sample.
You might need to order a custom to match the texture and density if you want a perfect match, but starting off with a stock to experiment with is a good way to go.
If I were you, I'd also go for an Ultra Fine Swiss Lace which you probably wouldn't get with a stock.

Below are some pics of the shape of the front contour I think would work well and achieve what you want.
