From what I remember, there wasn't really a single switch date. USB-C ports on phones became common years earlier, but USB-C to USB-C cables and chargers really started becoming the default around 2022–2023 as more manufacturers adopted USB Power Delivery and stopped including USB-A chargers. Apple moving to USB-C and the EU charger regulations also accelerated the transition. So your 2022–2024 estimate sounds pretty reasonable.
