Just about any dark or reddish exotic hardwood works. Burled walnut would be fine. Buffalo horn is traditional.
Ivory (or maple) forend tips don't do anything for me, but some folks still like that sort of thing.
I once got a good deal on an Oberndorf Mauser custom in .35 Whelen at an estate sale. The grip cap and forearm tip were elephant ivory. Took me a while to get used to it but now I like it. FWIW, it is currently my favorite rifle. For the OP, probably ebony or some other dark wood would work.
