Depends on the Arabian. I've had two purebred Arabian mares. Both sweet, but one was spooky (Mia) and the other one was not (Lilly). Both were "please and than you" horses. One was easy to work with, and one was not. I've got a 3/4 Arabian gelding with a very hot non-Arabian sire who is the calmest, sanest horse I've known. The two of us have not 'bonded' in 7 years, but he is a darn good horse. We just don't like each other much.
My current go-to horse is half Arabian, half mustang. He's not as reactive as the reactive mare, but he spins up fast. Calms down fast, too...but he'd be a pee-poor beginner's horse.
I trusted both Lilly and Trooper with my youngest daughter when she was a total beginner. I traded Mia away in part because she was too much horse to live in a corral and be ridden by an old guy in the deserts of southern Arizona, even though we had done so for 7 years. I'm still unlearning bad habits I picked up as a defensive measure when riding her. That said, I doubt I'll ever meet a horse I like more.
If you are an inexperienced rider, don't get the initial experience on your own horse. Take lessons until you have, at least, a stable seat, gentle hands and some feel for horses.
If/when you are in the market, don't buy the breed. Buy the individual horse. Cowboy is a 13 hand BLM mustang, maybe 700 lbs and around 17-18 years old. He's too small for me (I'm 5'8" & 160 lbs). He's not pretty. He'll take advantage of a total beginner (he's had at least 6 owners and been a lesson horse). But in his own way, he's teaching me things about riding that I did not learn during 7 years with Mia.
I'm obviously partial to Arabians. But Cowboy is a darn good horse, and would be a great trail horse for a rider who has the basics down. The soul of the horse is not limited by papers or breeds. You can have a great 'bond' with a horse and yet have no business owning or riding her. You can have almost no bond with a horse and be a good working combo. And sometimes, you can meet in the middle. But I would no more limit myself with "Arabians only" than I would "black horses only".

I'm partial to Arabians, but don't limit yourself.
