It will be difficult with a new domain for a highly targeted keyword like planning wedding. The longer keywords you mentioned are more specific, but they all include planning wedding, so competition will be fierce. A better bet would be to try to curate local guides on planning wedding. I.e Austin.planning.wedding or something. I don't know if subdomains rank better than subpages though. Planning.wedding/Austin might be even better. There will still be huge competition for big cities though.
