There is also https://en.wikipedia.org/wiki/Digital_euro in the making. I think that would then also supersede Wero?

Portugal got mbway, Austria used to have paybox, there is iDEAL, sofort.com and generally besides the local country systems with de-facto European banks you get "SEPA Instant Credit Transfer" nowadays - however IBAN is "harder" to share than lets say the phone number your friends already got.
