Those are all social democratic principles representing the status quo of countries like Germany, Nordic Countries, or Albania. Markets still exist and managed by patterns of supply/demand. There is just a greater emphasis in elevating the floor for the living standards by crowning universal healthcare coverage and progressive taxations systems.
Radical Leftism, I'd generally classify as Maoism, Juche, Castroism or whatever the Soviet Union was. The economy is predominately planned, there is no freedom of speech, democracy, and trail to operate private businesses. It functions like a capitalist country with a "Vanguard Party" or deformed dictatorship instead of oligarchs controling the means of production and generally what is best for everyone. Historically, it has never transitioned into a format where the workers or common man control the means of production. There are exceptions like the SDF or Zapatistas but they have not displayed results on macro-scale.
