I will be making the structure from birch plywood for stability, and was thinking of using homasote for the top - easy to tack or glue track right down, and pretty forgiving when it comes to any changes down the road. Any thoughts on this?

Hi Jered and welcome!
I used homasote for my track base over plywood. I like it for the reasons you noted. Humidity, as you probably know, can be a real issue with homasote but if you paint it (both sides) that seems to greatly reduce the risk of warping. Painting it a ground color also aids in scenery construction. My basement has some temperature and humidity control issues but I've never had roadbed warping problems on the layout over the 18 years I've gradually been building it.
