Cats are a good choice. If possible get a pair, so they can be company for each other. Keep in mind that while independent, they do need active interaction. e.g. 30 minutes a day of active play, especially for indoor cats. A bonded pair is a smart way to go. Can't commit 30 minutes to active play? Then is it really fair to a cat? A bored pet can be anxious and often times that anxiety results in destructive behaviours. Clawing, counter surfing, etc.
Like dogs, most kids, and autistics cats flourish with routine. Play with them before you feed them. Feed them on a schedule and stick to it. People often free feed out of guilt for leaving their cats alone for long periods of time. This can and does often devistate their health due to overfeeding. Recent studies have shown that free fed cats live and average of 3 - 5 years less than schedule fed cats. This is due to weight management and its associated diseases like diabetes, renal failure, and cancer risks.
We have two dogs and a cat. One dog is immensely labour intensive (enrichment activities). The other is lazy to the point of resembling roadkill. Potato Cat tags after Rue Dog, so he gets included in the games and puzzles, but he needs enrichment of his own. Cat tree, several tunnels, scratchers, bags, springs, ribbon, etc.
Just as a heads up most shelters and rescues do NOT declaw any of their cats. The practice has fallen out of favour due to the long term impact it has on cats, as well as for the pain it causes. It is also one of the main sources of problem peeing, a major reason cats end up at the shelter in the first place. The litter hurts their paws. A majority of vets also refuse to declaw because it is basically removing the kitty's toe tip to the first knuckle. Get a cat, it comes with claws. Plan for it. Potato has six on two floors with a perference for corrugated cardboard.
My previous cat was declawed as a kitten nearly two decades ago (Mom's decision, I was still a kid at the time.) She ended up with noticable arthritis in her front paws later in life.
Invest time in your cat and it can be an immensely rewarding experience. I had CatCat another twenty years after I pulled her out from under our neighbour's shed. We've had Potato Cat going on three years. He turns three at the end of the month. He has more friends on social media than I do, but he is also my common ground ambassador. The majority of people in the US have pets, 53% have dogs, 35.7% have cats.
