i believe that raminit isnt done via a blob anymore. you might as well read the official docs.
coreboot isnt even in the main tree yet! you have to use libreboot unless if you want to hunt down mate kukri's branch and go off that. you also have to use deguard to disable intel boot guard. It is more work than ivy bridge, which is why I use libreboot; its all done for you, its reliable and updates are done by someone else (you dont have to update your own payload yourself and recompile and retinker etc).
32 is great for editing and such, but I do assume that one would be using linux, and in that case, I can consistenly open over 100 tabs in firefox and do programming and have electron apps open on the side on KDE plasma with no issues, no out of memory errors. Things do get squeezy and noticeably slow at those extremely heavy workloads; for heavy tasks of course get 32 but if 16 can do you that far its fine.
I even won a hackathon with 16gb of ram on an X230, if I can do that and be productive even at home its enough. macOS is just very RAM heavy, theres always at least 50 weirdly names background processes active.
