It’s hard to answer this question quickly.
In general the Anglican churches combine Catholic and Reformed piety and theology. There are people who are just about Catholic, but there’s also a strong Reformed wing. It teaches beliefs that have been historically Christian, but holds to core Protestant ideas such as justification by faith.
It tends to have liturgical worship, i.e. fairly formal services.
Most Anglican churches are moderately liberal on social issues. E.g. the South African Anglican church has no prohibition on ordination of gays, although they oppose gay marriage.
The US version, and I suspect the SA version as well, is what I’d call “mainline.” These are the churches most directly going back to the original Reformation (in the case of the Anglicans the Reformation in the UK, which had some differences with the Continental reformation), with traditional worship and piety and relatively sophisticated theology. E.g. they accept evolution and other types of modern science, which many Protestants don’t. They typically don’t consider the Bible inerrant, though some members do. By that I mean that they recognize that the Scriptural authors were inspired, but also had ideas that came from their 1st Cent background, and that they don’t always agree with each other.
The world Anglican communion (as well as the US branch) is currently being torn apart by arguments over homosexuality, though the SA church seems to be broad enough on this topic that you may not see much about it in your church.
More “conservative” Protestant churches tend towards more legalistic ethics, often reject evolution, and hold to Scriptural inerrancy. Their worship is typically more informal.
If you’re happy with the SA Anglican church, I’d stay there. I’m part of a different mainline church (Presbyterian), but I consider the Anglican tradition a good compromise between Catholic and the best of Protestantism. In the US, I'd say there are similarities to other mainline churches such as Methodist, Presbyterian, Lutheran etc (as long as you're with the mainline versions of these churches and not the more conservative versions). But I don't know anything about the churches in SA. I checked specifically on the Anglican church and your own congregation, but not more widely.
I can tell you that there's a very wide variety of flavors of Christianity. In some cases you won't see much difference if you just go to Church on Sundays, but you will as soon as you get more involved. In other cases you'd see quite an obvious difference, both in the style of the service and what is taught. The difference is large enough that many people in CF would consider me "apostate," i.e. non-Christian. And visa versa, though I'm too polite to say so.
Differences include fundamental questions such as what the Gospel is, and the relationship between Jesus and God, as well as practical questions such as whether Paul's letters should be treated as examples of thinking out questions in a Christian way or whether we are committed to doing things exactly the way he told the churches to which he wrote to do. One of the most visible differences is in how we treat various questions in sexual ethics and the role of women.
Anglicans hold traditional theology, but tend to be more open to new ways of thinking about theology than more conservative Christians. In ethics they tend to be more open to the possibility that some some of Paul’s instructions were specifically for the 1st Cent situation, so they typically accept full participation of women in leadership, and allow a bit more flexibility in sexual ethics that conservative groups. But again, this is an observation on the US branch. I’m not sure exactly about the SA Anglicans. (I note that there is or at least has been a female bishop. Various indications are that it is similar to the US branch, though probably slightly more conservative.)
Anglicans here typically participate in the Traditional Theology forum (under General Theology), the Anglican forum, and for those who are most interested in the liberal end of the tradition, the Liberal forum.
A lot of the discussion on those forums tends to be about theology and worship, more than personal things about your life. Personal questions are certainly appropriate in the Anglican and Liberal forums. I think Traditional Theology as well, though that's more a theology discussion group. However I’d feel safer with the answers you get from Traditional Theology, Anglican and liberal than some of what you’ll see elsewhere here. Take a look at the kinds of questions asked in Christian Advice, and the answers, to see what I mean.
(I should note that I’m an official Ambassador for Traditional Theology, although my theology has some fairly non-traditional features.)
