I use this site to turn things into tokens - https://rolladvantage.com/tokenstamp/

It takes whatever image you plop into it, so at that point you can turn anything you want into a token. As far as what to make the images with, I’m not entirely sure, since the ask is kinda vague. What are you looking for in the tokens?

As a DM, thinking on your toes has been invaluable. The ability to come up with ideas, explanations, and more on the fly has helped a lot at work in meetings when unexpected things come up.
