Personal preference likely will be most important however here are some tidbits about white compared metallic blue.
Car might stand out less against the snow but this will be less relevant when there is buildings etc. White shows lines of car more (gap for bonnet etc) which can change car appearance.
White likely cheaper to buy originally and to repair. Less expensive-looking.
Car might be less easy to warm as darker colors attract heat.
Insects more visible if front of car hits. Mud more noticeable. Other materials like pollen or road dust or salt less noticeable. Less bird poop as birds may prefer blue, like the sea, to poop on. Check the appearance of white and blue cars in your area to see what is relevant?
Influencer Kris Rifa drives around Norway and seems to prefer white.
I'd be interested which color and reasoning you end up with or if you choose differently
