He was believed to be a saint in life, and as you mentioned, a descendant of Gods. I don't know much about him in detail either, but as far as I've understood it by reading Touhou wiki and a few other sources, (some non-touhou) there is a lot of doubt about his deeds, and even his existence. There is even a book called "Shoutoku Taishi ha Inakatta", "Shoutoku Taishi never Existed" or something of the like.

Which is why, probably, he was an obvious choice for ZUN, considering the theme of Gensoukyou.

As for Miko's power-level though, I feel like we don't know enough about her yet. She's probably high, but I would hesitate to place her in 2nd tier like the list posted.
