Hellooo!

I got my first ever apple watch last week and I got the series 9 41mm. So far it's been great, it has been found useful but I feel like I want to do something with the watch's band. I got it in midnight so every colour fits but I don't know which style I should go for. Any ideas? I don't want it to look childish or tacky. Also, do the silicone screen protector thing works, I feel like I'm about to scratch it every 2 seconds.
