Have a look at:
https://www.jethrocarr.com/2014/06/16/thunderbolt-and-other-macbook-hardware-issues-with-linux/

Seems to include some tips on getting suspend/resume working with
thunderbolt (untested).

It also recommends that thunderbolt should be unplugged on boot... (also 
untested)

Note it is from 2014 however.

I had no problems with grub.

This system seems to have intel based chipset.

Also note I am using the kernel with stretch backports, due to problems
with the intel graphics mentioned in another email here.
