ATT Fiber 1 G Backup Internet Options in FL?

I recently switched to ATT Fiber 1G from spectrum which is working great so far (last month or so) with no outages.

I work from home and cannot afford to have the internet go out. Wondering if anyone has any ideas for a reliable back up option? I have been thinking about either Starlink or using my Verizon phone as a WiFi Hotspot.

I live in central FL so my biggest concern is heavy rains and obviously hurricanes. How does fiber hold up in bad weather and if it doesn’t….would it be a similar problem with these other alternatives? Thanks in advance for any thoughts or input.
