The language choice is based on what project you want to accomplish and the platform you chose. An Android app (there are a billion smartphones) you would pick one of the IDEs and use Java/Kotlin. A project on the Raspberry Pi would be C/C++ or Python or whatever. A web project would be javascript /CSS /HTML /React talking to (huge list of things). Games would be on one of the 3D engines and a supported language. Various flavors of AI use different languages and libraries. Pick a project you want to build. That would narrow your choices. Then search Stack Overflow for opinions /recommendations. The APIs on the platform of choice restrain the languages used.
