My thoughts
Necessary slot? Yes. As a primary color (with yellow and magenta), cyan is one of my top three mixers. I like to use cyan colors to mix greens; they’re also no slouch at mixing violets.
Favorites: I go for a Phthalo every time because they have a wide value range, high tinting strength, high transparency, everything I look for in a mixer. Phthalo Blue Green Shade or Red Shade are classics. Green Shade is very versatile for mixing, strong, inexpensive, and common in tutorials. Red Shade is great for one-color skies. Phthalo Turquoise is also one of my favorites because it has a wide value range and mixes great greens.
Some of the colors listed here are more “bonus colors” than colors that can carry the job of a primary cyan; among them I’d list the ones that don’t get very dark, such as Cerulean Blue, Manganese Blue, and Cobalt Turquoise.
