If you're not going to be doing 360s and tailwhips you probably don't need to buy a small FGFS frame. It's not abnormal to have your parts resting on the toptube of your frame but the bike still fits, mine does. If I end up having to wait at a long light and stand over my bike I just tip my bike over to the side a bit, it's not a reason for me to buy a smaller frame that doesn't fit me just for that purpose.
