I'm wary of "systems" like this, whether Marxist, Georgist, Hayekist, whatever. The idea of a system is too attractive, and I think a lot of these ideas therefore attract undue approval and adherence.
A la carte, experience and evidence would seem the way to go. Unfortunately, if you adhere to a system, some of the items on the buffet are just off limits.
I would suggest some of the essays regarding Mutualism and Georgism at C4SS. They tend to do a decent job breaking down the problems of capitalism without smothering you with thick language.
If that seems a bit too much, I recommend first essay in Robert de Fremery's "Rights vs. Privileges" as a short overview of George's concepts.[0]
