Are there plans to document how fenestra works and how one can get started w extending this beauty of a project? Would like to understand the event system a little better

Hey! Absolutely yeah.
For now, the Fenestra-Template repo has some comments about how to use everything and also ImHex serves as a great example of how things work. Especially the event system is basically 1:1 identical.

The event system basically lets you define events using EVENT_DEF(EventName, ParameterType1, ParameterType2); in a header and then other code can subscribe to that event using EventName::subscribe([](auto x, auto y){ });. Then every time something calls EventName::post(1, 2);, all subscribers get executed with those parameters

EVENT_DEF(EventTest, std::string, int);

int main() {
    EventTest::subscribe([](const std::string &value1, int value2) {
        fene::log::info("First function called with '{}' and '{}'", value1, value2);
    });

    EventTest::subscribe([](const std::string &value1, int value2) {
        fene::log::info("Second function called with '{}' and '{}'", value1, value2);
    });

    EventTest::post("Hello World", 123); // Prints "First function called with 'Hello World' and '123'" and "Second function called with 'Hello World' and '123'"
}
