The official NVMe Pi Hat has been out for months, I guess I should get one, or maybe an alternative. I just bought a NVMe USB enclosure which has appalling performance, way worse the USB/SATA.

I prefer the NVMe base boards rather than the hats to keep the top side clear for fans and GPIO cards.
I've got the Pimoroni NVNe base on one (with the pibow coupe 5 case and official cooler - make sure you get the long PCie cable), the other is in the Argon NVMe case (from PiHat) which has an NVMe base board and cooler built in. The performance of both boards is identical with the same drive.
Note that the performance of NVMe drives can vary considerably though.

Does the rPi5 use U-Boot for NVMe. I've had a lot of problems with U-Boot not recognising NVMe drives on a Orange Pi. The latest Armbian Boot loader is working, I need to have a look to see if they are using U-Boot, I'm pretty sure they were in the past.

I had no problems with either of mine recognising the NVMe. I was using USB SSDs with each of them, so I booted from a temporary SD card, cloned the SSD on to the NVMe, and then rebooted with just the NVMe present.
