Append "Instrumental" to your search results and look for non Spotify playlists (i.e. community tended). I feel like every time I pick a "recommended" playlist that swears it is non-vocal, I wind up hearing some horrific voice samples ~30 minutes later.
My go-to deep work music when I don't have time to think is "techno bunker" with random playback. Some genres do not lend themselves to vocals very well and I hide inside of these as appropriate.
My other strategy with vocals is to listen to music in other languages, preferably stuff like German or Korean (you might even catch me listening to kpop while coding). Most romantic languages I can decipher enough to get distracted.
