I love tea and after about 1:00 i will start drinking it and drink it all day. Strong and with milk and sugar.
I only like one kind, long leaf, unbroken orange pekoe (orange being the color not the flavor) and i buy it by the kilo. There's a particular brand from turkey (originally no doubt from sri lanka but imported through turkey) that is incredibly cheap and incredibly good. I think the long leaves release less of that bitter tannic flavor and more of the (natural) aromatic flavor of the tea leaves. I have a basket type tea strainer that fits hanging in the cup (bodum makes one and otehrs too) because they hold more tea than those teaspoon tea balls, and less crumbs fall into the cup.
I can't stand green tea, it tastes like unsalted spinach soup to me and, Koukou, apparently black tea has the same substances as green - what i read is that it came out about green tea being "good for you" because they had only tested the green tea. Like the red wine story, red grape juice is just as good, as is red anything practically.
I don't like fruity or flavored teas. (I don't like "flavored" anything). I don;t want my tea to taste like hand cream (jasmine, rose, etc)
The only exception to the milk and sugar part being iced tea which i make with lemon and a boiled sugar syrup that is almost caramelized - i think it probably doesn;t have a different taste, but the placebo effect works with taste too and i find karkade (hibiscus) tea to be awful hot but great cold, with sugar. It's bright red and very appealing.
But to your question of storage of the little boxes Koukou, what about a sort of spice rack of the sort that is like those old typographer's boxes, a bunch of boxes or else short shelves, that you can hang on the wall? you could fit those little teabag boxes right in there. The colors of the ends of the boxes would show, and being a lot of them, the display would be nice. And being in a city kitchen with limited space, the wall is the best storage.
