I don’t see anything in the list the OP gave that couldn’t be addressed to an audience of all ages.
There are two issues here: subject matter and expression. The subject matter, as you note, isn’t objectionable per se. However, the
particular expression of that subject matter is a much more delicate question. Parents have the right to be the primary educators of their children; if they decide that their 8-year-old shouldn’t be subjected to certain expositions of particular subject matter, their desires must be respected.
Moreover, not all homilists are equally adept at phrasing their homilies in ways that are respectful of all “audiences of all ages.” Some are – and these homilists are due profound respect for their skill. Some, however, are less adept; and their (well-intentioned but poorly executed) homilies can do more harm than good. For us to stand in judgment of them, I think, is a rather inappropriate response.
In addition, it would seem to me that pastoral considerations are relevant in this context. A parish that has had the blessing of solid homiletic catechesis is well-prepared to receive certain exhortations during the homily; a parish that is less well-prepared – or a community that is less well-catechized – is not. In the latter case, it might be more prudent to seek out other contexts in which fundamental catechesis might be presented. In these situations, such ‘remedial’ catechesis is necessary, it seems, in order to prep congregations so that they might be able to receive particular messages from the pulpit during a homily.
In short, the answer is this: just because
you’re primed and ready to receive certain messages during a homily, doesn’t mean that others are. Therefore, castigating your homilists for not delivering such messages might come closer to ‘rash judgment’ than to ‘admonishment’ of our clergy.
