......Plain filler would stand out like the proverbial sore thumb & getting a fair match with pieces spliced in would be difficult as the wood grain is quite striped & would certainly show up.
If the damage is deep I would splice pieces in. It's the traditional method, usually a diamond shape plug, and it's easy to do with a sharp chisel. Unless you look carefully it won't show up, a patch of filler certainly will.
