Looks like lot of things changed since last time you actually used an apple device. Apple has swipe down to search for a while now which doesn’t require reaching up. Safari has option to put url bar to top but default is bottom for more than a year now which is reachable. I personally never understood need for third party keyboard apps but that’s personal choice. 3rd party app store is valid suggestion but that seems to be coming in future update. but might be restricted only to EU. You could probably access it by setting iPhone region to some country in EU but that’s speculation.
Showing how to cope with a loss. I don’t mean death i mean like losing in a game or failing in math. I never lost as a kid so didn’t develop how to cope with losing. So when i failed for the first time in university and i dropped out(Completed it later). but to this day i never attempt anything out of fear of losing. Im still trying hard to overcome it. So don’t let your kids win every time when playing board games or something.
