Yunnan Golden Needle for a black tea

For a white tea, Silver Needle, aka Baihao Yinzhen.

For a green tea, I like a basic gunpowder green tea, possibly with fresh mint.

Hojicha is a great anytime tea.

For cold brew tea: Adagio’s Thai black tea, Genmaicha tea, or hibiscus mint tea. Kukicha with fresh mint also makes good cold brew.
