I use this dock along with a 5120x1440 monitor as my main docked environment. Had absolutely zero issues: https://eshop.macsales.com/shop/owc-thunderbolt-dock

Bought it four times now (two cities, one setup for each myself and my partner). Neither of us have had an issue with any.

I looked at the Caldigit but had some reservations based on online reviews. Ultimately a coworker recommended a Dell WD19S and specifically said to look for one on eBay - took about a week of hunting and bidding but I scored one for about half retail and have been quite happy with it, it just works all the time. The laptop in question is a Dell xps13 running Ubuntu 20.04.

If you can afford the caldigit, it’s a premium unit but seriously good and quite popular.

I use 2 Thinkpad P27u-20 monitor, they have thunderbolt 4 with daisy chaining, ethernet and power delivery. Basically the docking station is in the monitor.
