Late September is, well, sort of late. You might run into some weather problems at altitude, but if the forecasts work in your favor, the park is pretty much wide open to whatever your abilities will permit.
Here's a few to consider:
Tuolumne to Yosemite Valley via the JMT is popular. Tuolumne to Yosemite Valley via Vogelsang and Merced Lake is nice. Grand Canyon of the Tuolumne via Glen Aulin is another. 10 Lakes Basin is pretty cool. Mix and match. Be real about the weather, trail conditions, and what you can pull off in the time you have. The number of permits issued at that point in time go way, way down, so you most likely can do just about anything without reservations on a walk-up basis.
