<5.5", NFC, 32 GB, works with T-Mobile's Band 12/VoLTE, <=$300

I'm looking for an Android phone that...

Required:

• Is around 5"
• Supports T-Mobile's Band 12, VoLTE
• Has NFC (I used Android Pay all of the time now)
• Has 32 GB of storage
• Is around or less than $300

Would be nice to have:

• Waterproof
• T-Mobile's Wifi calling
• USB-C

I don't care about the CPU, camera, or screen quality/resolution.

The only phone I've found that meets this criteria, although it's $350 instead of <$300, is the Moto X4. I'm not sure I want to buy a phone this late into it's life cycle.
