Food hampers - themed to what they like. A nice throw or rug for keeping warm. If they're relatively mobile, theatre or restaurant vouchers. Photo books full of their old photos if you're close enough to have copies.
Another one is nice picture frames with pictures inside they would like, of friends, family, themselves etc
My elderly great aunt (now deceased but lived until 98) used to love Fortums hampers. She enjoyed the cakes, biscuits, tea etc well beyond Christmas and took great delight in sharing her posh goodies with visitors and her home care team.
She also loved the photos in nice frames I gave of her family so she could add to her sideboard (as she put it) and talk to people about her family.
