DisplayPort is better for high refresh rate connectivity. This is a good cable:
Realtek RTL8153 is gigabit only. Thus if a dock advertises 2.5Gbps, it's likely using another chipset such as Intel I225 or Realtek RTL8156B.
CalDigit TS4 has the Intel I225 and DP 1.4. It's also $400, which is steep.
You're better off using an inexpensive USB-C to DP 1.4 cable with a dock that has TB4 passthrough ports:
That depends on what you need:

I personally have this dock:
Satechi often has 20% off sales making the dock $240. They have a 15% off coupon that works nearly all the time IPADOS, which makes the dock $255.
The dock charges the host at 96W PD.
The dock's ethernet adapter is based on Realtek RTL8153. It causes high CPU usage as macOS does not have a good driver for it. You're better off buying a USB-A 2.5G ethernet adapter based on Realtek RTL8156 like this one to hook into the back of the dock:

The audio jack has a lot of hiss. I would avoid using it with low impedance headphones. Either buy an impedance adapter or use a USB soundcard. I use a cheap USB-A soundcard:

The dock has three downstream TB4 ports. You can use two of them to run two 4K@60Hz monitors via USB-C to DP or USB-C to HDMI cables. This cable is VESA certified and supports HDCP 2.2 for playing DRM'd Netflix 4K:

If you have $400 the CalDigit TS4 is highly reviewed:
Hey, I saw that you posted some stuff about the ports for the Prometheus 17. I'm trying to hook it up to the Samsung G7 odyssey monitor. Is it possible to do a USB-C to Displayport? I have tried 4 different cables and none of them work.

Get this which will work 100%
USB C to DisplayPort 1.4 VESA... https://www.amazon.com/dp/B08B3XNZGS?ref=ppx_pop_mob_ap_share
Well, I don't specifically own that one but I do own this one that does work. However it doesn't have extra ports, it's just USB type c to displayport 1.4.
According to Requirements:
Minimum: Additional Notes: Available DisplayPort (Version1.2) and USB (2.0+) Port required
Recommended: Additional Notes: Available USB (3.0+) Port required for Headset Pass-Through Camera
1 x DisplayPort 1.2+ for headset display
1 x USB 3.0+ for headset cameras
I would suggest trying out other cables, like this one.
This is working great for me. Running 4K 120hz tho.

EDIT: Are both connections usb-c ?
