However I'm trying to decide on a circular polarizer filter

A linear polarizer is better.

for enhancing sky colors and minimizing reflections.

What I like most about polarizer is to enhance the color of grass,
flowers, and trees, ...

I hear that circular filters can knock 2 f-stops off a lens. Since I
already have a slow lens,

This can be a problem.

would a more expensive filter take less of a
toll than a cheap one?

No.

What are the considerations? Any recommendations?

Just get a cheap polarizer, to see whether you like the effect. If you
want a better one later, maybe with a better lens, get a multicoated
linear polarizer.
