Me short, too
Having a 30 inch inseam, I see the problem as well as you do. It is a pain to have to check the seat height as part of the specs. Fortunately, there are options that will allow you to change the height as well as a few standards that are fun, handle well, and have low seat height.
The Ducati Monsters are all relatively low-seated, and should fit you well. As a platform, the monster is a great stock bike that can be modified to be about anything you want it to be.
Also check and see if the bike you want has a seat with lotsa foam. My bike had two inches of foam on the seat and was shaped wide, spreading my legs and lifting my feet off the ground. A simple trip to the local car upholstery shop fixed the problem. I had the seat lowered a full inch and the profile rounded. It is now much more comfortable and my heels reach the ground. As a side benefit, it put me into a perfect riding position so I could lean against the tank with no weight on my arms for those long days in the saddle.
Third option is to buy boots that have relatively high padding and lift your heels a full two to three inches off the ground. I haven't had to resort to that yet.
Fourth option is to lower the suspension, but that gets complicated and can be dangerous.
But keep *****ing about the problem. I had a Yamaha SECA II. It was perfect as far as seat height, and I probably should have kept the bike, but I was seduced by an Italian. Since then, the manufacturers have been going tall.
