IKEv2 is a nice mix of speed and security, but is developed by Microsoft and is partially closed-source. That means that individuals cannot check some of the code for anything that might be malicious.
OpenVPN is the standard for security and is fast, but it is bulky and bloated and can slow down older devices. OpenVPN is also completely open-source which means that anybody with experience with its programming language can check it for anything malicious at any time.
WireGuard is a newer VPN protocol that promises to be faster, more stable, and more secure than other protocols, but is still in development. There are other proprietary protocols based on it, such as NordVPN's NordLynx.
Feel free to correct me on anything I might have gotten wrong!

My main question would be the level of security and confidentiality with an email hosting service in Milwaukee or elsewhere.
Confidentiality level
Exchange hosting services provides a copy of the data on the client machine as well as a copy on the server itself which provides immediate backup of critical data. Traditional hosting services would require a specified backup of the client data be initiated to provide the same level of data recovery in case of a crash or corruption.
A "confidence" is a small secret; something that you are told that you should not pass along. For something to be "confidential", then this is something that should be kept private, and not distributed. In the military, "confidential" is the lowest level of security classification, followed by "Secret" and "Top Secret".
WPA2 AES is the best bet for SOHO network. You can implement safer method using RADIUS server authentification on enterpise level.
