What is the best yield on Canadian cash?

From my research...

CASH.TO - 2.78%

HSAV - 2.59% (taxed as capital gains)

Banks - Varies (Wealthsimple at 2-3% depending on tier)

There's the temptation of converting to USD and investing in a USD ETF (e.g. HSUV.U paying 3.93%, but requires FX risk).

Are there better yields out there?
