80gal is a good sized tank. With zebra danios, you're going to need other species that are voracious eaters like the danios, otherwise the danios will out compete for food. Danios usually stay up top and so do angels so I wouldn't suggest them together.

If it were me, I'd look for a center dwelling centerpiece fish. Then you'd have the danios up top, corydoras on the substrate and something in the middle. Perhaps gourami are center dwelling fish I do not know I've never kept them

+1000 for black neons, they are such an overlooked species but i kept a school once in a 75gal with discus and corydoras and they were just perfect.

also +1 for rainbowfish. the LFS near me, a full on saltwater reef store that has a small freshwater side, has a huge display tank with rainbows and congo tetras and they look great together.
