A 10" slider will cut most of what you need laying flat, the bigger issue is cutting nominal 6" trim that is standing up against the fence. Personally I would get a non-slider in 12" size, they don't take up nearly as much room and will cut a 5.5" board at 45 degrees. That being said, I have a 10" Milwaukee non-slider straight MS, no bevel capacity. Don't know if anyone sells a saw anymore without beveling features.
