I always use 1/4" seam, except on HST. As long as you're consistent, the seams and points should be fine. I've even used 1/2" seams (on enlarged blocks, for dog beds) and my points, etc. still matched up just fine.
If I'm using thicker fabric and am afraid of the thicker fold taking up too much space, I simply press the seams open, instead of to the side. Works for me.
