It sounds promising that both Frontier and TorGuard servers are in Miami, as long as your company websites is only blocking by the location of IP addresses.
Regarding the slow WireGuard speed, the best test is to go to a public hotspot with your Slate Plus WireGuard client and try it there. At least you now know that the Flint WireGuard server works.
The GL.iNet free DDNS service is fine to use, like a number of people on this forum, and you have to make sure the WireGuard client config file has the correct DDNS domain name for the peer endpoint. If you want a backup, you can add a 3rd-party DDNS, either free (e.g., freedns.afraid.org, dynu.com) or paid (e.g., noip.com), but you have to set that up yourself manually. If you really want to be “super safe”, you can pay for a business account to get a static public IP.
It would be ideal if you know a family member, friend or someone on this forum who could test connecting to a VPN server in Miami and try accessing your company websites to see if the verification shows up, even without actually logging in. You do not have much time to have everything ready before you leave.
