Rick's Cinturato P7 ASPlus are for sure a good option for you. But they are still a V-Rated tire, very high performance, and thus have a bit firmer ride due to stiffer sidewalls.
If you are more concerned with a nice quiet grand-touring sort of ride, rather than the performance feel, there is the Bridgestone Turanza Serenity Plus and the Michelin Primacy MXV4. Both are H-rated rather than V-rated and have the softer sidewall. I have the Brigestones on my XJR winter wheels and the Primacy MXV4's on our other car. [These will probably be the next winter tire for the Jag, too] Both have a superb ride and all have worn perfectly even across the tread. The Bridgestone's also have an asymmetric tread design, so still have that sort of 'high performance' appearance many like.
If you don't show in Champion, all of these options are possibilities for you.
Good luck!
