You've pretty much nailed it.
Fast Advance decks tend to want to score 2-2-2-1 or 2-2-2-2 (or 2-2-2-0 with Sleepers). The exception is Cerebral Imaging, which can do 2-2-3 because of the ability to combo FA a 5/3 with Efficiency Committee and Shipments.
Glacier decks such as HB and RP usually want to play some 3-pointers and some 2-pointers so they can score 2-2-3, (3 pointers are harder to score but save deck space).
Flatline decks are usually the weirder ones. Jinteki PE and Weyland can score any weird combination of 1, 2, and 3 pointers, as their agendas tend to complement a kill strategy, (House of Knives, Fetal AI, Philotic Entanglement, Project Atlas, The Cleaners, Posted Bounty). In those decks, you don't just score the agendas for the points, but because their abilities tend to help your kill. If at any point you get close to 7 points or the runner is for whatever reason careful or protected from your kill, you sort of have to decide based on the agendas left in your deck and how many points you have how to score out, or threaten to score out, the rest of the game.
