I have two 4K 60Hz monitors plugged in my work MBP (M1 Pro, or is it Max?) via DP over USB-C (not TB) basically every day. The MagSafe and HDMI ports sit unused, and I wish these were more USB-C ports instead.

My personal Mini M1 can't handle two DP over USB-C displays but can handle one DP over USB-C + one USB-C to HDMI. I also wish the two USB-A ports were USB-C as well.
