I researched the front diff issues, and found a couple interesting products
wavetrac LSD -- ive used these in a number of RWD and AWD race cars over the last few years and really happy with them. I had no idea they offered this for the raptor 8.8 front diff! its oddly listed as fitting 2011-2012 only (will also fit all the way to current). I see a few people on here complaining about torque steer with a front LSD (likely due to tires + 4A). either way it makes sense, and is something I am OK to compromise with to get more traction
front diff brace - I see some companies make a "front differential brace" that attaches to the unused diff bracket/ mounting ear - have any of you tried one? I was going to order it but saw they do not support 2021+ (lowered front diff mounts). Interested to know your thoughts, will probably design something myself to provide additional rigidity

do you know if anyone has broken mounting ears off with an additional brace attached? or cracked a diff housing? some pics i found largely show a crack in the housing, with a few of the ears cracked like you mentioned

older stock-ish toyotas with gears are reliable and capable (i still have a couple yotas i cant bring myself to part with).
