Few movements self-identify as “Socialist”, at best it’s a taxonomical label. Attempting to talk about the finer points of socialism is akin to debating the pros/cons of “Animals” – it’s an overly broad topic and doomed to spiral into bike-shedding over semantics as soon as the conversation starts to look interesting.
With that being said, let’s talk about some more concrete terms – apologies in advance for wielding only slightly less clumsy terminology in my bullets:
Socialized Medicine: Healthcare is a human right. I am pro human rights.
Unions: Mostly positive. Nothing’s perfect, but come on… you’d have to be blind not to see and feel for how exploited lower-class workers are without them
Democratic Socialists of America: I’m a member – that means I like them. I think their platform represents the ideal incrementalist approach to improving the current status quo
European Welfare States (e.g.: Denmark): Too fuzzy to have a solid opinion on, but certainly a battle-tested template. I like most of their ideas most of the time
Marxism: A genius body of economic philosophy, but increasingly out of place as time marches onward. I’d be for a by-the-book implementation (insofar as that’s possible) in 1923, but not 2023
Maoism/Leninism: Not exactly success stories. It’s easier to appreciate their noble ideas & intentions with the distance lent by history, but that’s altogether different from "liking"
Communism: As a whole? I think the template holds promise and can be made to work in a modern context, but viability =/= realizability. The world would have to get turned upside-down first and it’s questionable exactly how many of us would live through that… but never say never.
