Vietnam - Remote Working to US - Experience with Speeds and Different VPNs

HI Folks,

Talking to my company and its likely they'll approve me to work remotely in Vietnam for a month or so and curious as to what your experience is using either a paid which i guess ppl like NordVPN or ExpressVPN and if anyone has ever built their own at home using WireGuard or OpenVPN

Has speed been at least great enough for Teams Meetings with share screen as I rarely get on a Face Video Chat.

Has anyone done remote desktop work to a machine that is in the US and had any laggy experience as really, an RDP session is basically streaming the changes you make on the machine you RDP into.

Anyone ever create their own using WireGaurd to their home and worked remotely?

General data privacy, what are people using on their phones to access emails or even sensitive data such as logging into their bank app?

Thanks for your help and time!
