Can you suggest gift items for my man's birthday?

He's turning 27y/o in November

He's very simple n not much into fashion n all, among all the gifts I've given before loved gifts like socks set xD and a small toolkit.

He's into game like league of legends, genshin impact, he's a researcher, likes singing, reading

I'm very clueless, planning on getting some chocolates he wanted to try and I'll try baking a cake. In addition to that I want to gift him something

I don't have a huge budget
