I might have enough room for another grape in my city lot. I have
Catawba and Concord right now, two plants of each.

I've read that Niagara grape vines grow fast and maybe too fast, that
they take over a space quickly and like to spread.

Is this one to avoid because of this? Is it a good grape for
winemaking?

Any other commonly available varieties that I might want to grow? I
don't have unlimited space.
