Probably the most important thing to consider is how large are your hands. Some designs are what I would call, "gaunt", and some are "fuller". If you need a certain weight in the wood for your rifle, you need to calculate the finished dimensions that will really fit you, first.
If you plug a light piece of wood into a gunstock designed for a heavy piece of French Walnut, it won't come out right. Too heavy of a piece of wood in a hand filling design may just be too unbalanced and heavy. And your hand size (glove) will impact what size forearm is best for you.
I would pay very special attention here to a stock blank made from Myrtle Wood, from the Oregon Coast. Different minerals make these a law unto themselves.
The Mauser 98 action is a known quantity, but the barrel profiles and the stock designs have to work together for you.
