What Pokemon have good type coverage for the end of S/V?

Question

I want to know what kind of Pokemon I should get for the end of S/V. I want some Pokemon with good type coverage. Could someone help me out?

I am talking about finishing up the four storylines.

Is it possible to find and catch a high level Flamigo in SV? Bulbapedia's location pages are very incomplete right now.

Pretty sure the highest is lvl 50 around lake casseroya.

In that case, Flamigo is probably one of the better choices. I know Lucario can also be found at a high level and can use good coverage moves.

I'm not sure if just sharing a plethora of Pokémon both with good coverage and accessibility at a high level is enough to answer the question, but Garchomp, Dragonite, Bisharp, Toxicroak, Floatzel, and Gyarados are all fairly good Pokémon that fit this criteria.
