Packets containing frames besides ACK or CONNECTION_CLOSE frames count toward congestion control limits and are considered to be in flight." So as per RFC-9002, it means that ACK and CONNECTION_CLOSE frames do not contribute to congestion control limits. On the other hand, RFC-9000, section 12.4 has a Table 3 (https://www.rfc-editor.org/rfc/rfc9000#frame-types) which states: "The "Spec" column in Table 3 summarizes any special rules governing the processing or generation of the frame type, as indicated by the following characters: ... C: Packets containing only frames with this marking do not count toward bytes in flight for congestion control purposes; see [QUIC-RECOVERY]." However, in that table, the CONNECTION_CLOSE frame isn't marked with the "C" character and only the ACK frame is. This appears to be an oversight in that table in RFC-9000.
