You're on the right track. I've ridden cross country numerous times, the last few which have been on a VFR or Superhawk.
I like Zero Gravity double bubble windshields for a little extra wind protection. They also have a "sport touring" model for a little more coverage. Givi also makes taller than stock shields. Be careful though, too tall and wind noise becomes distracting.
On that subject, I wear earplugs; usually the cheap disposable type. However, I had a custom set made at a show I attended recently; $45. Noise is a factor in fatigue. At the end of a long day, one will be less fragged if hearing protection is used.
I'm big on tankbags so that I have different gloves, electric vest, water, camera, hat (for off bike), map case, etc. right at hand. I use RKA but there are so many on the market.
If traveling far and additional clothing is required, you'll need more luggage. Again, I use RKA saddlebags and tail bag, but lots of other good stuff is out there. The RKA folks will color coordinate luggage with bikes, though, if that's important.
I find that my Aerstich gear, either the Roadcrafter or Darien outfit offer the most versatility. They are vented for hot weather, mostly waterproof for rainy weather, and the Darien has a removable electric liner for cool weather. I love my leathers but it's hard to beat the textile stuff for versatility. There is a lot of that on the market, too.
As you can see, it's not just the bike, but what you wear, too. It takes a bit of thought to go touring. I took off 30 years ago on a 750 Honda with a blue jean jacket and one pair of gloves and a duffle bag full of clothes. I have learned quite a lot since then.
