Aron

I might be biased here, but I do think Aron is a great beginner steel pokemon. Arons are easily trainable and fairly social, so it's easy to get them used to eventual other pokemon in the house. They're also a very typical steel pokemon I would say, in that they're likely one of the first pokemon to pop up in everyone's mind when you mention steel.

You need to give them regular metal supplements in their diet. Ask your veterinary but in general regular hardware store bolts are perfectly fine, just check the materials and avoid excessively sharp spikes. Some people worry an indoor Aron might end up chewing on metal fixtures inside the house, but so long as they are fed properly they won't try to attack your things. They aren't extremely active and can be kept in flats too, provided that you let them have a regular walk. Don't let them get bored, or they may start headbutting your walls and no one likes that.

Their evolutions are definitely more a handful, but the good thing is that Aron requires a lot of battling in order to evolve. If you aren't a trainer, it likely won't happen. At most, if they regularly mock fight other pokemon, they may reach their Lairon stage - although rarely. Lairon is basically a larger and more stubborn version of Aron, if your Aron evolves you likely have enough experience to handle a Lairon. Aggron is the real problem, but again if you aren't a trainer there is basically zero chance of accidentally evolving an Aggron

Klefki

This small pokemon has one major advantage: it's small. Yes, I know, shocking. But the thing about steel types is that they tend to be very heavy, and a small pokemon can be way more manageable. Klefki is still fairly heavy for its size, but you can move it around or keep it in your lap without risks. It's very rare for a Klefki to damage the owner's house or objects, too. They are a very relaxed species and won't act out unless given a very good reason to. They're very smart, and can learn plenty of tricks and commands without much of a fuss.

Of course they have some things you should be aware of. Their obsession with keys is one. If you want to be sure they won't steal your house keys, try getting plastic covers for them, Klefki is much less attracted to keys if the metal isn't exposed. While they become very attached to the owner, they can be a bit standoffish with strangers. They're definitely a pokemon that gets attached to only one or a few individuals, and they are best kept alone as they can get territorial with other Klefkis.

However, being more solitary means their socialization needs are low, and they are pretty good for people who don't want to keep multiple pokemon, or that don't have a lot of time. They also need very little exercise and are perfectly happy being couch potatoes. Just don't neglect them, give them attention if they want it, and invest in some keys. A few key blanks a month are perfectly fine, and Klefki doesn't eat much aside from those

Klink

First of all, Klink isn't for you if you want a pokemon you can cuddle with. Aside from the general uncomfortableness of cuddling some gears, Klinks don't like physical contact in general and it's best to only handle them sometimes. If you don't mind this, then they are wonderful pokemon to have.

For starters, they're smart. They can be a bit stubborn and not the easiest pokemon to train, but they can also learn a lot of commands at a far faster pace than many other pokemon. They are very curious and inquisitive and love being taken to see new places. They also adapt very well to other pokemon, provided they aren't too high energy and don't try to touch them too much. Once they grow attached to you, they enjoy following you around all the time to see what you are doing. Their diet is mainly metals based, but they do take a few berries as well.

If you are worried about it evolving into Klang or Klinklang, it's not going to be a problem. That rarely happens without regular battling involved. If it does evolve, Klang and Klinklang have very similar temperaments to Klink. They're basically a Klink that needs more food and space.

Bronzor

Bronzors are unfortunately quite misunderstood. There's all sorts of legends surrounding them, more or less based in reality, and so lots of people assign them powers that they don't have. In truth, Bronzor isn't much more powerful than the average commonly kept psychic types. They don't bring knowledge from forgotten civilizations or anything of the sorts, or at least they're very good at pretending they don't.

What they are good at is being your friend. They have a very good disposition and they're smart cookies, making them easy to train and handle. In nature they tend to group together, so it's suggested you either get two or house them together with other pokemon so that they don't get lonely. They are also fairly cuddly for steel types. Just don't try to polish them! They all hate it for some reason, even getting them clean if they dirtied themselves is a small struggle.

Be warned however that Bronzor's lifespan is... complicated. Many live a few decades, but there are rare reports of one living past a hundred. Their evolution, Bronzong, is even more dramatic in this, with a few of them being thought to be thousands of years old. It's very rare from what has been observed, but no one is quite sure what triggers it, so be prepared to plan ahead.

Togedamaru

A wonderful little round ball of a pokemon! Unfortunately not as soft and pettable as its shape suggests, but it's so cute. It's very easy to train and gets along well with other pokemon, although there can be some conflicts with electric types. The main issue with Togedamaru is that it likes electricity, and that can lead to problems like trying to stick its paws into electric outlets and short circuit your house. However, it can be trained out of it, and nowadays many stores sell outlet protectors.
