I think that would indeed be the perfect person. But... I think naturally any good quality is going to have a bad counterpart so to speak. It's that yucky balance in life. The sun always comes up, the sun always comes down etc.
For example, I've found that truly loyal people tend to have the most fucked up personal lives. People with strong DO come across as fake as hell at times even though I realize that's not that what the function is about. But still, it's very much the perception about it.
If you're approachable, which is good, people might also think you're easy to manipulate or you're trying to manipulate them. If you keep to yourself though, that also obviously brings it's own set of prejudgements.
We can just never win. I really like your ideal though. Sounds like somebody I'd want to marry and fly off to heaven with lol.
