My current phone has all the things you listed except MST (never heard of that before though), and I bought it specifically for those reasons. Made by Xiaomi who still seems to want to give users features for some reason. Unlocked, rooted, custom rom, the whole shebang, I’m very happy with it.
It does still have a small front camera hole and a big back camera bump, but I don’t mind those personally. Though I do wish the camera bump wasn’t off centre. And like someone mentioned, I do wish it had an indicator led somewhere.
