which pants to go with the blazer i bought?

hi all!

so i recently thrifted this blazer for job fairs at school and i'm trying to decide which pants to get with it. pictures below are of the blazer with and without flash (the darker one is more accurate, just wanted to show that there's a navy tint to it) and the other screenshots are the pants i'm considering getting. would appreciate feedback on which color will look the most professional/clean or if anyone has suggestions for similar pants in a different color on some other website i would also love to look at that!

i was originally leaning toward the mink grey ones but i need more opinions before i launch on this because they're a little pricey lol

also i dont know if this helps at all but i would consider myself like.. soft autumn maybe? very neutral toned though i might lean slightly warm (but i usually wear silver jewelry because my face leans cooler than the rest of my skin) and the soft autumn colors seem the most accurate to what i have in my wardrobe and what i usually like on myself

thanks!
