What seeds should I use in `invoke_signed()` for PDA derived via `create_with_seed()`
This isn't working for you because create_with_seed doesn't generate a PDA! Use Pubkey::find_program_address if you want that.
So your code will look like:
const SEED: &[u8] = b"My Seed";...

Are there any rules as for what derived path can look like?
Technically, it could be anything, but it probably won't be supported by any wallets or tools.
The derivation path like m/44'/501'/0'/0" defines a tree to follow from a seed to the actual key, so ...
