The aggressive strategy would be to apply for both, AmEx limitations do not prohibit it (90 days minimum between applications for the SAME card). Understood “few months to hit the minimum spend”, perhaps estimated tax payments (as many of us do) might help?

BTW, based on many datapoints here (other threads) you might start receiving more offers, so called targeted NLL (no lifetime language) offers for biz Gold and biz Plat. Some people have managed to get a biz Plat (almost) every 90 days and a biz Gold (almost) every 90 days.
