Do you have any older, clear, pictures of the beak? I don't really see anything in the first photo, but I'd bet there is a very miniscule misalignment even then. Unfortunately cross beaks start off as a miniscule misalignment so small they're generally not visible and get worse as the chick grows.
How quickly a chick feathers is only an indicator of gender IF they are specifically bred for feather sexing. It requires a specific combination of genes and most hatcheries aren't breeding for it.
I would be nervous too if I had one chick feathering that much slower, but 1.5 weeks really is...
If you have those links handy I'd be interested in reading. Personally I don't think it will be an issue with a small backyard flock. I suspect you'd probably need 20+ chickens and minimum space for it to be an issue (more like a commercial set up) but that's just a gut feeling, I don't have any...

We tossed 4 eggs at day 14. Two clear, one early quitter with a blood ring, and one that looked like it quit around day 7-9. Air cells were looking a little small, so we dropped the humidity to 30%. We'll probably candle one more time at lockdown on Thursday, but it looks like we're going into...
Congratulations, it's always so much fun picking breeds!
We are also limited to 6 chickens in town and there are 4 people in our family, so each person chose a breed and we voted on the final 2. We ended up with:
Rhode Island Red
Blue Laced Red Wyandotte
Cream Legbar
Meyer's Cookies and...
