Oh and about maintenance and repairs. Short answer: no, I don’t think you need to worry about any maintenance for at least 10 years and then, you’d be better served buying a new instrument. Your mileage may vary and sometimes these instruments break. The better you treat them (no liquids, no slamming, no dropping, no exposure to direct sunshine all day), the better they usually last. In normal use a normally functioning piano will last you a long time with no maintenance save for wiping it with a damp cloth if the keys feel sticky. An acoustic piano will require at least a hundred dollars of maintenance per year if you want it to work and sound properly. Digitals are almost free in comparison.

Also: a good pair of headphones is good to have. It is important the pianist feels they can practice without remorse or wondering if they are disturbing others. The possibility to play silently is one of the main reasons for getting a digital instrument.

There is a pretty vast difference between a digital and an acoustic and for advanced players it is a real concern: they should get to practice on a real instrument. But that is after playing for 10 years and if the pianist is gifted. “Normal” players playing for their own amusement can play on a digital all their lives in my opinion. I’ve been playing for 42 years and I still have a Kawai upstairs and a hybrid Yamaha downstairs as my main piano and I am between advanced and very advanced these days.

The Korg B2 is another popular choice for beginners. Never tried one myself so I can’t say much past that.

Generally, any quality digital piano such as the ones you’ve been looking at will last quite a few years, given that you care for it properly.

Edit: About maintenance, there’s hardly much you’ll have to do beyond just cleaning the pianoand making sure not too much dust accumulates (I recommend just covering the keybed with a large sheet) Issues with the internals should be taken back for potential warranty claims.

The Casio PX series has received fairly good reviews. I didn’t much care for the older models, but the new (and very slim) PX-S1100 and the slightly older S1000 felt pretty nice. I think it would serve you well. One thing to keep in mind is that I don’t recommend the X shaped stands. They are cheap, but ultimately get in the way of learning to use the pedals as well as are really annoying when they get in the way of the legs.

A new pianist can maybe get away without using a pedal for the first year, but it is an essential part of playing and depending on the teacher, it will be needed sooner than later.
