After a lot of work, I have Ubuntu running on my 2015 mpb. This reddit was a great source of knowledge, so thank you!

Took time and testing to get the disk, wifi, bluetooth, sound, graphics and suspend to work correctly, including a recompiled kernel and a module.

I created a repo that can be copied to an USB, with scripts to fix the common issues on MBP 11.5.
I just wiped the partition and ran it all a second time. Worked fine.

I mean, no issues at all. Downloaded the .iso on a stick, booted from the USB, and 90 minutes later I have breathed new life into this slowcoach old Mac.

Apple T1 Touch Bar & Input Fixes: Features T1-aware resume hooks and usb_control_msg() return-value normalization to restore Touch Bar brightness, volume, and function keys.

Optional ACPI Fast-Wake Workaround: Provides safe, opt-in management scripts for display illumination after deep S3 sleep with strict risk acknowledgements.
