I have done +12 langs and who knows how many data formats, sql/dsl dialects and all that.
One simply trick I do is use different Editors/IDEs for each lang, with distinct themes.
So for example, I associate work on python with Sublime, json/js with VS Code, Rust with IntelliJ, Android with Android Studio (yes, I know I could do both in IntelliJ!), Swift with Xcode.
It super handy this way because one big trouble of do all in the same UI is that "switch" bring everything at once, instead when all is their focused UI have things side-by-side with different themes/fonts let everything be distinct.
Weirdly, I can't like the same theme/font across everything, I suppose some stuff look nicer here than there :)
