(I should mention that I do not like Le Havre at all, mostly because I find it tedious and too long, so keep that in mind if you consider what I write here.)Le Havre realistically takes 2 hours or more, so it is probably out. It is also harder to learn than any of the games you have listed.
On the other hand: If you like Burgundy, that makes you a medium-heavy, even a borderline-heavy gamer and you need not fear games in that category. However: The time issue is still there and Le Havre is a loooong game.
I would suggest that Agricola, while so different from Le Havre that they are hard to compare, is the better game.
I would also suggest that you consider Caverna. It is, basically, a revised and less stressful Agricola with some elements added. Of course, you have to accept the somewhat geeky dwar-theme (I wish he had gone witht something else, but there you are.) The rules are longish, but well-explained and most things make sense, so they are easy to remember.
My choice (listed by level of preference) would be 1) Caverna 2) Agricola 3) Le Havre.
