Since you'll be able to train on club trainers, it probably makes sense to buy a forgiving sport plane instead of a trainer. The best one ever designed is the Ugly Stick, continuously produced since the 60's. It will fly and land just as slowly as a trainer, but handles wind 100 times better. The only downshot for newer pilots is that it doesn't self-correct.

On the topic of size: There is more to it than being easier to see, even though that is definitely part of it. Bigger planes get tossed around less by wind turbulence, they feel slower for the same airspeed due to the scale effect on your perceptions, the bigger wheels do handle bumps on the ground better, and they (at least to me) are easier to work on since they don't have so many tiny and delicate structures.
