Some suggestions: Card, biscuits for the staff room, cute post its/pens etc, class materials (books, fun science things), vouchers (coffee shops or books?), a charity donation to a charity that you know they support (aka do not get if you're unsure). It all depends on the person. I've gotten herb pots and cacti too, but the kids knew I liked cooking and I had a cactus in my classroom.
Nothing wrong with wine/ chocolates, they're standard presents and the thought is appreciated, but being honest - they are a bit forgettable. I don't think that really matters though, but personally I'd steer away from giving those.
I think my favourite present ever was the sponsored elephant from dswt, or a class butterfly hatching kit. Cards and letters are really the best by a mile, though. I have a box of them from over the years that I look through every now and then.
Not mugs, handcreams or anything homemade. I'm not into Christmas decorations made by the children or anything Best Teacher.
