Welcome from the Bay Area of California. I'm in the same boat as you are and I've been sewing for 40+ years!
Reality standpoint - if you are a perfectionist or just hate to see the unmatched seams, then baste the joints first, check them, THEN stitch the seam. If something doesn't match, your seam was either off or the block was cut wrong. First choice, redo the seam. Second choice, tear it all out and recut the block.
I'm doing a Disappearing 9 Patch (D9P) right now and having conniption fits now on this issue. I've got the feet and the seam, but am not consistent in how I do my seams. Since I don't sew frequently, I'm not in practice.
You can do it - but just get used to Jack (the ripper)! Welcome aboard.
