I don’t have honey or maple syrup? What’s my next choice?

depending on the recipe: Agave syrup. Or, plum, apricot or sour-cherry jam (would benefit from a bit of sharp "contrast" flavor provided by either shallots, scallions, onions some dry powdered mustard). Dates or date syrup.

Other sweeteners on hand...sugar, agave syrup, golden syrup (British).
In a pinch, you could use jam or fruit, especially dried fruit, which will have more concentrated sweetness.
