For most landscape work the filter factor does not change. You are exposing for the unpolarized light, not the polarized light, so you can use a fixed filter factor.
It's a different matter when you are using the polarizer to shoot through reflections. Then you have to meter through the filter.
A linear polarizer is useful if you are making a variable ND filter. The front filter should be either a linear polarizer or a reversed circular polarizer. Otherwise a linear has no real advantages.
Because of the greater sales of circular polarizers these days, you can usually get a better selection of circular polarizers than linear.
