Rimmel BB Cream in Medium would give you a bit of coverage but still would look ultra natural - if you wanted to even things out a bit. I honestly don't think you need it though, you have very clear looking, lovely skin. I honestly wouldn't put concealor or powder on it, even though the Mercier powder is lovely - a BB cream will be all you need.
Elf monochromatic lip, eye and cheek stick in glistening peach or glimmering guava would look great on you. Great for days when you don't want to faff and gives a nice pulled together look. If you want to splurge a bit more Stila do a convertible colour that does the same thing, it comes in a compact and I think the shade Lilium would be good on you. If I remember correctly, that one has a peachy warmth to it.
As someone else said, a brown mascara and perhaps a hint of brown kohl. Rimmel kohl is nice, or for higher end, I'd personally recommend MAC. Max Factor do nice brown black mascaras.
For brows, if you want to splurge I'd recommend Glossier Boy Brow in either a tint of your choice - brown would be good, depending on your preference, or the clear version.
For a cheaper brow fix L'Oreal do a nice Brow shaping and plumping/ fixing gel - again brown might be nice here.
If you want to add a touch of highlight Vita liberata do a nice liquid one, it's called Luminosity - get the golden version.
That's all I'd recommend honestly, you're naturally gorgeous, so you only need a light touch to enhance.
