Update: The single plug is sold out, but you can grab the 2-pack for $23 with the code G458OE9X.
It may not have the brand recognition of Belkin or TP-Link, but this smart plug does all the things you want it to do, for half the price. $13 gets you an Alexa-enabled plug that doesn’t cover the second outlet and doesn’t need a hub to work. You’re gonna want to buy a couple of these.
