Only thing i would recommend from personal experience is to try and find word substitutions for the more “technical” terms that could be offputting or confusing to “normies”. Don’t use “proletarian” and “bourgeoisie”, use “workers”/“working class”/“the employees” and “owners”/“corporate elites”/“millionaires and billionaires”/“ruling class” or something like that. Most people are very receptive to the ideas themselves, and they instinctively understand even fairly complex Marxist concepts, especially if they have personal experience being exploited, but the messaging has to be packaged in more generic populist terms for people who have been subjected to a lot of anti-communist indictrination, otherwise it can trigger a kind of mental tripwire and they just shut down and stop listening to what you’re actually saying.

Of course it depends on your interlocutor what kind of language they will respond to most favorably, and there is a time and place for technical jargon too, but regardless i’m a big believer in the idea that if you really understand a subject well you should be able to use simple language to explain it to a layperson.
