Polyurethane bushes are a popular option on the 147 for the upper wishbone, anti-roll bars (front and back), and most (if not all) of the bushes at the rear.
Most popular over here are the Purple Powerflex option, but there are many others (Strong Flex etc.) available. Polybushes are often a bit harder, but to be honest it's not a determent to the ride in my experience. You could try and seek softer polybushes if you wanted (e.g. for Strongflex: Red = SHA 80, Yellow=SHA 90).
I have a set of Purple Powerflex bushes fitted to my upper wishbones - whilst they were a little harder, the ride certainly isn't appreciably rougher at all. Mine do squeak quite a lot at the moment, but that can usually be prevented by a liberal application of the correct grease at installation.
Lower wishbones tend not to get done on the 147/156/GT simply because they do not wear out as quickly - and by the time they do wear out, the balljoint is often worse for wear anyway.. Makes sense at that point to replace the entire arm rather than try and re-bush it for the balljoint to fail shortly afterwards.
