The problem you'll encounter is that most consumer electronics are made in China because it keeps the price competitive. So you really just need a reliable brand. The main reason to avoid quite a few Chinese products would be the plug sockets.
So.while I haven't used it and can't guarantee it's not made in China (also assuming you are in the UK), then TP-Link's Kasa smart power strip looks like a good option as all that range work with HA. I've used other TP-Link products and been happy with them so it would definitely be an option I'd look at
