Struggling to sound natural: When should I actually use the 'voseo' in Argentina?

I'm planning a move to Buenos Aires and I've spent years learning standard Spanish, but now I’m constantly freezing because I don’t know when it’s appropriate to use 'vos' versus 'tú'. I feel like I’m constantly overthinking the verb conjugation shifts on the fly. How do you all handle the transition to Rioplatense Spanish without sounding like a total tourist who memorized a single phrasebook?
