We don't have a very good understanding of the genetics of many of these traits. Intelligence is especially thorny, involves numerous genes, and is probably only about half hereditable which is actually reasonably high. We're likely to get a bunch of tall people, until everyone remembers they die younger due to cardiovascular strain. We'll probably wipe out most single gene hereditable diseases, which will be great. We're also somewhat likely to see fads around eye color in "designer" babies. We may also get people selecting for a single gene that make for great endurance athletes. Anything much beyond that is science fiction in the near future. The knock on effects of tinkering with more than a handful of well understood genes is going to be really dangerous. Quick Edit* There are around 1000 genes that have some bearing on intelligence. The 22 most impactful together account for 5% of variation.
