When things are more normalized, you may consider visiting a high quality spice shop. You'll pay a pretty penny but on all that you're saving from not eating out, you'll find it well worth the while. Even if you go in "without a clue," the staff will guide you on your way. The Oaktown Spice Shop (Oakland and Albany) is my first choice in these parts. You can purchase in small fractions that they bag, so you can sample things without a large commitment.

Also, if you do not watch Lidia on PBS, you might consider watching her show. Of all the cooking shows out there, you'll find some easy, practical and delicious tips that, even if you don't make the recipe completely, you'll get some good ideas.
