Very well explained. A couple of points I will add.
Clover is often also an indicator of too much moisture, something a bit hard to control during the cooler months.
As mentioned, feed the lawn in spring or once the days are consistently warmish. Don't bother feeding now as it won't offer much effect or benefit during winter.
Avoid "Weed-n-Feed" type products. These simply burn away broad leaf weeds (clover inc) and leave the root system behind, allowing the weed to recover and return. Good stratagy for selling more product, hey?
Using a broad-leaf weed killer will kill the whole plant. Which you use will be dependent on what type of lawn you have. For most situations Couch, Kikuyu and Fescue are treated differently to Buffalo. So, if you have a predominance of Buffalo, make sure to choose an appropriate product.
We sell Searls products, so that is what I know. For general lawn weed control, look at Bindi and Clover Killer or Lawnweeder.

For Buffalo, use Buffalo Master.

Only trouble with that will be actually getting some. A lot of these have been on back-order for months now. Another Covid casualty.
