If you like fruity nuances Ceylon could be a thing, you get good quality without spending a lot

If you like darker, maltier and deeper taste, you can go for Assam, there is a lot of quality types and prices

I've got a feeling, based on the wording of your title, that you are looking for exact product recommendations. In which case your general location in the world might be helpful

As for the daily drinker black (in the European sense, right?) tea, though I like Darjeelings. They have a nice happy-fruity flavour

Earl grey. Can't go wrong

What is a non food quality tea? Pot pourri? What else could you use tea for?

That's a pretty open-ended question, but I think other folks have made some good suggestions.

Assam, Ceylon, and Yunnan teas tend to be the best in terms of price per gram, and can be found from multiple vendors.

Did you want specific vendors/recommendations?

I explore a lot of different teas, including the complicated world of pu’er. And I’ve found a bunch that I really enjoy. But I still drink a very simple Numi Breakfast Blend every morning 🤷‍♂️
