Best privacy-first tax software

I've been trying to wrap my brain around the options for weeks now, and the space is so chaotic and muffled.

I'm trying to find the best crypto tax software that collates all trades across wallets, optimizes for minimum tax using different methods (LIFO, FIFO, etc), and doesn't store your private data or allows you to pay anonymously.

Does anyone have any specific recommendations here?

Would be greatly appreciated.
