It's great that you are being thoughtful and assessing how you feel in outfits, as well as how they look. Having a coherent color palette and style is helpful and makes it easy to build from there.
I'm probably not the best person for advice on jewelry since I only wear plain hoop earrings, but from the jewelry you have made at the top I think the first lovely long necklace (because of it's length and the pale contrasting color) has a lot of promise to be worn with current outfits. I'm less sure about the two shorter necklaces, mainly because of their length, and that they don't have the 'bib' volume that I'm more used to seeing at that length, like the great necklaces in your finds below. I think your bracelets if stacked together on one wrist to have volume have good possibilities as well.
Other places that you can add interest to an outfit (still keeping in mind your style adjectives with each choice) are in scarves, footwear, bags, and sunglasses, even lipsticks if you do that. A pop of brighter color, a white, or a metallic in small doses can add a lot of interest to my mind to an outfit of navy and gray, and could work with blush and terracotta as well.
Maybe don't buy a lot of accessories at once but try one or two, and take some photos to ask for feedback or just for yourself to evaluate how you like the overall look of the same outfit styled in many different ways.
