My husband is fairly similar. We usually buy something 'big' between us as a main present so a new TV/games console/holiday/possibly a dishwasher this year. Something that we want anyway but maybe wouldn't justify spending the money on. Then we buy each other some smaller bits to open off the children.
This year I'm making DH a stocking of small things like chocolates, beard grooming products, a couple of books, Hygge bands, socks, etc. Plus nuts & a satsuma at the toe! Stockings are his favourite memory of childhood Christmases. We have decided to recreate some of the things from our childhood this year so I've bought some of the foil garlands for the ceiling and I'll be putting up lots of tinsel (I normally hate the stuff 😂). Is there something that your DH has fond memories of that you could recreate?
Previously I've bought him experiences, graphic novels, art books, lights for running, food/drink gifts, wallet ninja, geeky toys, t-shirts. Off the top of my head.
A comic book subscription went down well.
For his birthday I bought him an online escape the room that he can do via zoom with his workmates, they are all WFH so nice to do something together that doesn't involve work. No waiting around to be allowed to get together either.
From other threads, pizza ovens have been popular lately.
