Winstrol and anavar is one of the most common oral only cutting cycles. It is very effective but also really hard on your liver. Both anavar and winstrol are liver toxic oral steroids, using both at the same time puts a lot of stress on your liver. You will want to use a good liver aid supplement like N2gaurd with your cycle.
I like that you are adding cardarine/sr9009 to your cycle. The single SARM you can take for fat loss is a PPAR up regulator like cardarine or SR9009 ->

The nicest thing about cardarine and sr9009 is that they are not stimulants or hormones so they won't effect sleep, raise cortisol levels or anything like that. It'll cause a huge boost in fat loss with no side effects.
I would also add in a good natural testosterone booster like HCGenerate ES from n2bm.com or the SARM rad140 like @stevesmi suggested if you don't want to run a testosterone base with your cycle. It will keep testicular atrophy to a minimum and sort of replace the need for a testosterone base in the cycle. If you are going to run an oral only cycle, that is the smartest way to do it.
In this video I explain how to safely run a anavar oral only steroid cycle ->
