This looks less like a case of "which jacket?" and more like a case of "which style direction?".
You're getting somewhere with your style goals:
"Modern, simple, sophisticated, casual?" this sounds more like occasion descriptors than style descriptors. Someone might be Boho whimsical, yet some days, simple, others, sophisticated.
It sounds there is more to it than just a closet purge on a Spring-like afternoon. I would ask you: What do you mean by "modern"? Look at images you are attracted to on the Internet.
Or look at a celebrity whose style you associate with. Then pay attention to what style of jacket she wears. Or maybe, ask yourself, if I had to keep one and only one, which one would it be? Which one are you most tempted to reach out for on a daily basis? And that can give you a lead.
To me, jackets 3, 5 and 8 are totally different departures, and would be hard to co-exist in the same reduced capsule wardrobe.
I actually quite like 1, contrary to others, on you, because of its proportions, and how it cinches your waist. It looks cool on you. And goes well with the pants' style. I think what throws people off here might be its pairing with a white top, you already being blond. Maybe with darker colours such as a purple, violet or periwinkle top? Or even taupe?
To me, 5 looks dated.
I don't like 4 on you, both for the hue and the cut. It looks too long, not form fitting enough and hides your athletic, proportioned figure. Sorry for being brutal.
7 looks cute, put together, but not with these pants. I'd see it with a skirt such as an A-line.
8-9-10 would be keeps.
