Is it worth avoiding burning fuses? I was just going to update this console legitimately to play PLG. If I do update with choidujournx will it affect my ability to do this?
You would only be updating with choidujournx to re-install the boot0/1 you need so you can dump it properly and then restore your nand.
Doing this will not affect your ability to update normally after restoring.
Since it sounds like you want to go completely stock, then no. Avoiding burning fuses isn't worth it in your case. (You
might miss out on future warmboot exploits, or coldboot if you're on 3.0.1 or below)
Though I would still recommend keeping auto-rcm on until the point where you toggle it off to dump your clean boot0/1 and restore.
Just to spare the need of a jig if one isn't on-hand.

But to be clear, you need to upgrade/downgrade to the firmware using choidujournx that matches your original nand backup to extract a clean, usable boot0/1 right?
That's right, just keep in mind when backing up the target boot0/1 if you have autorcm enabled or not. As that is where it's installed.
Also isnt theres a way to extract the boot0/1 from a raw nand backup?
Assuming package1 is included in the Nand backup then probably. Though I haven't personally tried or heard of anyone else trying, so continue at your own peril with that.
Edit: Just checked
this page, seems like it's stored in some of the firmware titles.
