Please realize the poster said "cash", so recommendations like VOO or a bond fund have risk factors he's unlikely to accept as a cash alternative.
Money market, treasuries, or high-yield savings are all cash equivalents, to me.
Do all of those carry FDIC insurance?
We keep about $100k in a high yield savings account as an emergency fund, but I'm also looking for better options.
Well, if treasuries default, you're certainly going to have trouble with anything else you would consider.

High yield savings are FDIC insured (I think to $250k?). Money market may be covered by SIPC or something similar (?), but probably have incrementally more risk than the other two. During the financial meltdown, the potential for money market funds losing their $1 NAV was instrumental to the bank bailouts that occurred. So even if there's no formal government backstop, they're pretty darn safe.
Effectively, they're all close enough to be "risk-free" to probably just choose the highest rate and best timeframe term (maybe considering boosted rates for less liquid choices such as a FDIC-backed CD) between them. The bond funds like the one mentioned above all have corporate bonds in them, which introduces default, counterparty, interest rate, and other types of risk. Still likely to be pretty safe for short durations, but certainly riskier than the cash alternatives mentioned above.
