The biggest trade-off might be no F availability the rest of the day, be it on AA or OW partners, and a downgrade to business or even coach. I'd take an earlier SFO-DFW just to make sure you hold onto your F seat DFW-FRA. With SFO being prone to weather delays no matter what the time of year, I'd nevr risk a 45 min connection for international.
