You are using wrong command to flash the kernel.
You are using
Code:
fastboot boot boot.img
but you must use
Code:
fastboot flash boot boot.img
If you miss the 'flash' part, you will hotboot the kernel, that means this kernel is used for first boot after the flashing, afterwards the kernel on phone memory is used.

Which version of twrp are you running??
Because you'll need the modified twrp 3.0.2-19 if you are on the Community Builds. Official twrp doesn't work on Community Builds.

Stock recovery from OP will also give you a black screen unless you take the one from inside e.g. the CV 3.5.4 image.
But since you can't get into Recovery to flash it... Can you go into fastboot? Maybe someone can extract it. From there you can flash with
fastboot flash recovery recovery.img
fastboot boot recovery.img
will temporarily boot but not flash recovery.

Question fastboot still works if recovery bad?

I plan on building AOSP following the Sony insctructions. If for some reason I flash a bad recovery can this phone still boot in fastboot mode with a broken recovery? I'm asking because recently I had a friend brick his Asus phone because you need to boot into recovery to be able to go to fastboot. I didn't expect that since on my Xiaomi you can go straight to fastboot without recovery..

fastboot is separate from recovery on this phone, yes.
Also, you can test the recovery first without flashing by using fastboot boot recovery.img, it boots into the recovery image without flashing it.
