The SATA examples appear to be 2.5". mSATA is exactly the same speed and is the same size as a Pi Zero. Crack open a 2.5" SATA disk. You will often find an mSATA board inside. Anyway good mSATA SSDs live longer than most brands of notebooks. I recycled some 1 TB mSATA SSDs from notebooks with the USB 3 on a Pi 4 and saturated the USB 3 with no problems. They were, at the time, plentiful, tested, and really low cost.
Cheap NVMe often has newer chips that the equivalent SATA models and perform better. You will not see a difference with most use. I only see it when backing up a TB direct from one disk to another using USB 3.1 Gen 2 (10 Gbps). The main reason for choosing NVMe is the 10+ year life. I can reuse them with my next machine.
If you do run an SSD fast, they heat up. The USB-SATA chip also produces a mass of heat. A direct PCIe to NVMe interface should cut out the heat from the USB-SATA chip. If you are looking at a fully enclosed case in Australia with our current 40C days, reducing the overall heat is a priority.
The newest NVMe models product less heat per capacity but PCIe 4 burns more power than PCIe 3 and PCIe 5 is worst. I find the current best mix is a PCIe 4 NVMe running in PCIe 3 mode in the PCIe 3 setup as the PCIe 4 devices use a new generation of more efficient chips.
I look forward to your test results (in a hot room![:o]( "Surprised")
