Options are personal and linked to budget, so only you can really decide. There are types "need" options which you couldn't live without, and "nice to haves".
The fact you are thinking of adding a paint rather than DCC & wheels is an indicator to me that you are not quite yet at a place where you know what options you "need". Go and test drive cars, experience options and find out for yourself what ticks your boxes.
For me DCC and Dynaudio were must have "need", no question. That's because of the type of driving I do and my love of music. I wasn't buying a car without them. My thoughts on DCC can be found
HERE. Dynaudio is night & day different to the standard, so if music is your thing, make sure you tick the box.
Sunroof, nice to have, not essential, but I'd disagree with others who say you'd never use it, mine gets opened as soon as there's any sun, it makes the cabin feel much more light and airy especially on a Sunday morning b-road blast like I was doing yesterday.
Colour, very subjective, only you can choose. There's 'sporty/classic' colours, and there's newer subtler colours which can be seen as a bit more classy. I went for something that is befitting for a 42year old, and something that contrasts with the red detail. I don't like Oryx, I think it's quite a cheap looking colour, if you want a classic colour stick with the solid white.
90% Tints. Not for me, way too boy racer and not needed. The 65% tints are more than adequate. I speak from experience with 2 young children.
When I placed my order I forgot to tick the climate windscreen box, but now I've lived without it, I don't really miss it. Nice to have, but certainly not essential.
As for other options, Leather adds a touch of class and luxury to the cabin, electric drivers seat allows you to get the perfect driving position (again, needed if you do big miles), and the bigger wheels give it a bit of a better stance. But again, most options are subjective.
In short, add what you "need", then add what you want with any money left over in your budget.
