Need opinions on a wedding gift situation 😭

It’s my best friend’s brother’s Bengali wedding. I’m very close to my friend, but I barely know her brother personally. My mom is also invited and she’ll probably be the one handing over the gift at the biyebari.

Budget is around ₹600–700. The couple is young/Gen-Z, so I want something modern and useful, but also Bengali biyebari-appropriate and not something older relatives would silently judge 😭

I was thinking of some kind of home-use gift. Is that too practical/boring for a wedding gift? What’s the safest neutral gift in this situation?
