I've had good luck with the Elgato Thunderbolt docks. First their TB2 dock which after I updated to a 2018 13" MBP 4-port version I used with Apple's TB3 to TB2 adapter, and now their TB3 dock, which I've used with both with that same 2018 MBP and currently with a 16" M1 MBP. I've used the TB3 dock with a BenQ 32" 4K monitor via DisplayPort, but I recently upgraded to the Apple 5K Studio Display which is chained off the dock's TB3 output. I attach a variety of USB devices (keyboard, mouse, backup drives) and haven't had any trouble with it. It's over-priced at $250, but I picked it up from Costco last December for $100. I mention it because it's been trouble-free for me and it never seems to be listed in the reviews I've seen.
