That phone was first available 3.5 years ago. Better tech and longer support if you spend another ~$380USD. Plus, sell the unit that Apple is requiring you to exchange (even if broken), so your out of pocket might be only an extra $200.
If you are a light phone user and don't game or constantly stream movies and shows, that phone could do well for you, especially if you are on a tight budget. There is nothing wrong with that phone in 2021.
The only newer iPhone you could by around that price would be the SE2. You would get better cpu/gpu and longevity but it uses the last gen body and screen tech so not sure exactly what is important to you in a phone.. I've had the X since release and its been a great phone. No complaints or problems except the battery is getting a bit worn but I've used it daily for three and a half years and feel that's acceptable for it's age
