I know you said it's too time consuming, but it took me less than 15 minutes to get mine up and running with the Argon40 case. Argon40 has a M.2 (SATA B and M keys) to USB 3 addon part as well. So if you have a Pi4 that has already been configured to boot from USB, this is a drop in part. I find that my Pi4 has trouble maxing out the USB3 and SATA M.2 SSD's throughput. NVMe seems like overkill. https://smile.amazon.com/gp/product/B07WP8WC3V/ https://smile.amazon.com/gp/product/B07WP8WC3V/ - Argon ONE V2 Raspberry Pi 4 Case for the RasPi 4 https://smile.amazon.com/gp/product/B08MHYWJCP/ https://smile.amazon.com/gp/product/B08MHYWJCP/ - Argon ONE M.2 Raspberry Pi SSD Board What I like about this case is that the entire case acts like a heatsink for the CPU and Ram... and the internal daughterboard provides full size HDMI ports. IMNSHO, it's a no brainer if you already have a Pi... but even a NUC isn't a turnkey solution if you're set on Ubuntu. Still need to install that as well.
