Wax to finish and smooth out dining tabletop with deep gouges
Such a wax exists... but before we use it how deep xare these gouges? If you took a fork and dragged it deeply across a finished tabletop you could/would fill the damage with colored beeswax. Deeper gouges would necessitate different fillers, colored shellac sticks heated and melted into the holes works well. Typically, however, if you're sanding off the entire finish, you'd do that carefully and then look again at your problems. Sand only in dire straits..

Is the rest if the finish okay? Sanding destroys a good piece.. Proceed with great caution... do as little as possible. If it's just an ordinary thing - be careful here too - strip it gently, clean per instruction, seal with sanding sealer.. Adjust color, and THEN match a color. If its a good piece, there's a lot to know so you don't ruin it.
