The ASUS RT-AX58U (RT-AX300) is a good router to setup as a VPN.
Having a router setup as a VPN allows for any device in a home or office to automatically be protected.
This is much easier compared to installing VPN software on each device.
It also has the benefit of protecting visitors and any device that can not be setup with VPN software.
Asus routers can have third party software called Merlin installed which gives more options for using a VPN.

If you are new to setting up a router as a VPN using the default Asus options likely are best.

Setting up a Router as a VPN Using Merlin
The next step is to configure Merlin to connect to the VPN.
For the configuration below I use IPvanish VPN since that is the VPN I have which works well for me.
If you need a VPN see here for IPvanish VPN pricing plans.
If you already have a VPN the configuration should be similar.
There is a few protocols to setup a router with OpenVPN protocol being a popular option.
The basic steps is to download your VPN configuration file which has the server address and security certificate.
The security certificate will need to be copied and pasted in to the correct box.
Sometimes the Merlin software does not save the settings which I found will always save after Rebooting the unit.
