I'm using T14s Gen 4 Intel and sleep works for me. I'm using it in clamshell mode connected to external display 99% of the time, so I don't really use sleep all the time, but the few times I tested it, it worked. Actually every hardware peripheral, including fingerprint sensor, worked out of the box. I was pleasantly surprised by that kind of support.
I've got a relatively new p16s with a hybrid Nvidia/Intel GPU, and a p14s gen 5 with an AMD GPU, and I was able to get both of them to suspend by closing the lid. Not sure if the issue you speak of is unique to the P1 or not, but all my ThinkPads have been decent with Linux.
I’ve had issues with T14s for a couple of gens where the machine wakes up during the closed lid and runs the battery down. I’ve tried the usual troubleshooting.
This has been a non issue on Dell machines for almost 20 years.
