You want to look at relaxed geometry. You won't know how relaxed you need without
trying them, or a pro level fitting.

Try some bikes with traditional geometry. They typically had the bars level with the saddle or an inch lower. There were also often square, meaning the seat tube and top tube would be the same. This might well be a good choice for you. I have been drooling over this for years. Check the top tube length.

The Waterford version is even nicer, especially the 2200.
