For fraud, I think it's basically a matter of whether we can recognize each transaction. You don't actually need to download transactions for that; you can just skim your monthly statements.
For saving, that's tricky because there needs to be that recognition of what categories are likely to increase during retirement versus decrease. I gave that a single pass a while back, and now I have a count each month of those expense categories that will continue into retirement, along with a 12-month average, so I can get a sense of what my portfolio needs to be able to fund after I retire. For that, even though I have Banktivity, I also have to use a spreadsheet.
For taxes, I don't know if anything really makes that easy. It's hard to know what category breakdown you really need to know whether you're capturing all your tax benefit, and my financial software doesn't tell me "oh, by the way, you'll want to split that transaction since some of it has a tax benefit."
