Although some people will tell you to avoid hot blooded horses(Arabs, TBs, etc) as beginner mounts, breed is really irrelevant.
Your best bet is to find several horses, no matter the breed, who fit the description you are looking for --beginner safe-- and then go try them all out and see which one suits you the best.
The horse's personality and temperament determine its suitability for beginners, not its breed.
