I have not seen an inexpensive dock that has power delivery and 4K 60hz that only uses one port. I bought the Falwedi, I’ve not had any problems with it.
Falwedi 14 in 1 Type USB C HUB with to USB-C PD 3.0, 4K@30Hz HDMI, 3 USB3.0, SD/TF Card Reader, Multiport Adapter Dongle Compatible for MacBook Air Pro and Other Type C Laptops (Black)
I'm voting in favour of the Anker USB-C Powerexpand+ Hubs. They come in various shapes and forms, just make sure they support pass-through charging if you require this. They work with no drama.
