Luca feels so trendy to me. It only really popped up on baby boards a few years ago and now it just feels so tired. I'd actually prefer Luke/Lucas.
Honestly though all of your names are fine. I like Landon the least. I chose Simon because it is classic, versatile, and pretty rare. I have never met a Simon IRL.
I am finding that Luca seems to be popping up more. We like it because it fits Hubby's Italian heritage, and it isn't in the Top 100, but it does look like it's getting trendy.
