Hard part is software distribution. You can buy Chinese phones but what app store? Can focus on open source applications. Use F-Droid. I have an iPhone and an older Pixel 7. In the past I’ve had ZTE phones. I guess you can buy a Chinese phone with a Mediatek processor that has YMTC memory chips and … whatever else
