You could get a Celestron (or other brand) 8-24mm zoom to see what magnifications you prefer and get other eyepieces later. Consider Celestron X-Cel LX in fixed focal lengths if you prefer Celestron brand. (Don’t bother with the 2.3mm and 5mm with the latter only useable on rare nights of exceptional seeing (400x), i.e. not very often. and the former hardly ever unless you have a short refractor. In fact I wouldn’t go under 7mm on a 2032mm SCT but Mars can take more and often needs it if the atmosphere permits. Note planets will be small even at the higher powers but you’ll get used to looking at small discs.

What Dave882 suggested is a good spread. As to make, model, eye relief, apparent field, number of elements, correction; that is a personal choice and budget does come into it.
