Short answer
A SPIA is usually income now. A MYGA is usually a guaranteed-rate period.
Investor.gov, FINRA, and NAIC all frame annuities as insurance contracts with different guarantees, fees, surrender rules, and income features. A SPIA usually turns premium into an income stream soon. A MYGA usually credits a guaranteed rate for a stated period before later choices.
