I use a cellulose binder mixed with sawdust for these types of jobs. I essence what it allows you to do is make your own liquid wood of any colour you might want. I prefer this much over using things like CA glue. One of the biggest benefits is that you won't see it after finishing the wood (it is made of the same stuff as the wood itself after all). Unless you choose to create a contrasting filler, but even then you will see the filler not the glue. No more worries about glue stains. It sands perfectly too.
Sorry, it is in Dutch, but I use this product to fill gaps:
