If you get the spg,get the business version as you get lounge access. If not, if you up for getting multiple cards, you can probably get 2 to 3 cards with that 5k spend.
Also note there are 3k spend offers out there for both biz and personal. I can direct you to those if you want. I don't recall seeing them in my personal account. Someone referred me to their 3k link for biz verson.
