How to select coffee beans to buy? Beginner

Usually buy my whole beans at Costco with no real thought put into it, but recently been using my 1zpresso grinder and French press, and want to explore the coffee world a bit. Located in Brooklyn, NY so relatively close to roasters like Sey and Devocion. Question is, how on earth do I pick one?

Right now, on the Sey website, I see five different varieties I can buy. I guess if I'm going by tasting notes, the La Fila sounds nice because it has notes of cane sugar and pineapple, which are two things I like. Does that mean I'll be able to easily taste these two things in my coffee?

Also, are certain brew methods better for certain roast levels? If I'm drinking FP, is it recommended to use only certain levels of roasts (e.g. light, medium, dark)?
