Since it runs Android, you should be able to use any app in the store, right? So, let's say you need to buy train tickets, take care of banking, track package deliveries, check your PUK code, troubleshoot a wifi router, control smart lights, book a time for the dentist etc. There are a variety of random things where the modern world expects you to have either Android or iOS with you, so can this phone handle those situations too?

About 10 years ago, you didn't really bump into situations like that very often, so you could get stuff done by making a phone call, using a browser etc, but the 2020s are getting increasingly app dependent. It's just wild how many things you can't do these days unless you have a reasonably modern smart phone with you.
