Hey Chris,
Those ones look far more sensible.

I'd still look into a couple of trees that will grow fast and are tough as nails. Not sure about some of these ones you have posted simply because I just don't know them that well. Here are a few examples I've taken from the web of what you should be trying to find. It's close to bonsai but gives you both options and some work to do......

Start from as early as you can in your bonsai learning process to try to become as critical as possible and picky about the stock you buy. As an absolute minimum it should be an easy species and should have a visually satisfying trunk.
The maple and spindle look like you are on the right track. The Jasmine is a bit iffy, and the others may be fine as long term projects, but are not ideal as learning material.
More than anything, keep up the energy you have. It's great, and channeled into appropriate stock you will learn quickly and really enjoy the hobby!
Cheers,
Andrew
