Hi, when I was looking for wheels my criteria was a bit different but I can offer a bit of advice that might help.
Reading your desires for the winter wheels it sounds like buying either new or used oem wheels would be a sensible option for you?
If you didn't like the colour you could have them refurbished in the colour of your choice before fitting the tyres.
I wanted something none oem and both larger diameter and wider whilst remaining staggered width wise, I also wanted to achieve more poke (have the wheels further out) to fill the arches better. I knew I'd need particular offsets front and rear to get the fit I wanted without having to use spacers.
Like you I discovered that to be a limiting factor choice wise and with all my other criteria I found that my options were limited to a handful of brands.
The tool I used to help me choose was the configurator on this website.
Online Wheel and Tyre Fitment Calculator. Offset, Tyre Stretch and Speedo Error | Will They Fit
Which ever way you go, you will want to try to minimise speed error by maintaining a similar rolling radius to the current set up.
The convention for winter wheels is usually to go an inch or 2 smaller on diameter and fit tyres with a larger profile height to compensate, but in your case you'll struggle to find 17" wheels that clear the front 6 pot calipers.
Hope this is of some help.
