That depends on what your budget for one is.

I started out using a Belkin Multimedia Dock which worked well but limited to 30Hz video on its HDMI connector for 4K (2K and less works at 60 Hz). Used it for a year without issue:

I reached a point where I out grew that plus wanted 4K display capability and I am now using the OWC Thunderbolt 4 dock which is performing quite well:

There are many other USB-C and Thunderbolt docks/hubs out there and you can look around for one that has the right "fit" for you in terms of price and features. Just make sure they mention Mac compatible.

There are many out there. Take a look at Amazon. Most have the major ports for use. As an example:
