The best examples that come to mind are when ordering food. As examples:
• You speak English and Spanish and are ordering a burrito
• You speak Thai and English and are ordering Tom Yum
I imagine it could depend on numerous things:
• You primary language or ethnicity
• What sort of restaurant
• Who you’re dining with
• Who you’re ordering from
• and probably a lot more…
By how well known the word is by the people I speak to. English is usually not an issue. Germans speak english quite well. Languages’ Common phrases like yes, no, thank you are also often known. So I pronounce these as a native speaker would.
When ordering food? It’s a fine line when I don’t speak the language myself. I.E. ordering spanish couisine but not knowing spanish. I try not to butcher the pronunciation, but trying to lean into it would feel pretentious and awkward to me.
