If you have a Penzey's spices near you it would be worth a visit. They have every spice and herb imaginable and have an open jar of each one so that you can smell them (at least they did before Covid). I find that spices often taste like what their aroma is.
If not, places like Cost Plus World Market and some grocers (Sprouts) often sell various spices in little plastic bags and they are way cheaper....some spices are pricey and if you just want to try but aren't sure this is a good way to do it.
Also, some spices are fat soluble meaning the flavor doesn't really bloom unless it is mixed with a fat during cooking or preparing.
