So after all that .... any update on opinions of how bitcoin should be commonly measured?
TBC!
No, seriously, that's why we have the different units. If you're making micro-payments, cBTC or mBTC might make sense for now. If you're doing a huge payment, consider kBTC. If you use Tonal, you'll probably want to use ᵇTBC for most payments. In a few years, the value changes will probably adjust everything to mBTC/TBC (for normal sizes) and μBTC/TBCᵐ for micro-payments.
