Ranked choice voting (RCV) — also known as instant runoff voting (IRV) — makes our elections better by allowing voters to rank candidates in order of preference.
RCV is straightforward: Voters have the option to rank candidates in order of preference: first, second, third and so forth. If your first choice doesn’t have a chance to win, your ballot counts for your next choice.
RCV works in all types of elections and supports more representative outcomes. RCV means better choices, better campaigns, and better representation.

The single transferable vote is way better:
The single transferable vote (STV) or proportional-ranked choice voting (P-RCV) is a multi-winner electoral system in which each voter casts a single vote in the form of a ranked ballot. Voters have the option to rank candidates, and their vote may be transferred according to alternative preferences if their preferred candidate is eliminated or elected with surplus votes, so that their vote is used to elect someone they prefer over others in the running. STV aims to approach proportional representation based on votes cast in the district where it is used, so that each vote is worth about the same as another.
Instant-runoff voting (IRV) is the single-winner analogue of STV. It is also called single-winner ranked-choice voting and preferential voting
Seems like STV is an extension of ranked choice voting for the special case of multiple-winner elections.
