Same. We use the big end grain for non smelly veggies only, that essentially means onions and garlic on a separate board. This way I have so far gotten a way just wiping the end grain clean with wet paper or kitchen towels. Occasionally "sanitizing" with vinegar water mix. The board smells fine so far after about 6 months now. Beeswax seems to be a great help in this strategy.
Depending on mood, this can tbh pretty often lead into using a Hasegawa for the whole veggie prep on top of the end grain though. As onions are near always included. In the DW goes the Hasegawa then usually.
That or doing most of the cutting on the end grain and then a small separate wooden board for the smelly stuff.
Raw meat and fish I usually cut or butcher on a Hasegawa or a woodfiber resin board, each of which fit in the dishwasher. Cooked meat gets sliced or chopped on medium wooden board typically.
Honestly been considering moving the big end grain to some other, decorative use, but always lift it right back to the kitchen
