PBKDF2 and SHA256 are fine for all use cases and have libraries available in all languages.
argon2 has nothing better to offer. Practically there are 3 argon variants to chose from and they all require careful configuration. It's pretty hard to start with, assuming you can find libraries for it in the first place, last I checked it wasn't commonly supported.
It's a perfect example of theory versus practice. Argon is a researcher's wet dream, ideal by some algorithmic definitions, yet it has no benefits in practice.
