Enlighten me on your adjustable hole saw, please. Looks much less terrifying to use than this abomination

This one on Amazon has a pretty beefy cutter tip and the replacement blades are on the same page. I’ve not used it but it seems to be well received.

there is a circle cutter like this one but you will want a drill press capable of pretty slow speeds if you use that. I've heard horror stories about them coming loose and flying across the shop. I own one, but have never actually tried it out. mainly out of fear...

Except that's a corkscrew, this is an actual glory-holer

There are router templates you can buy for cutting circles. But you can also use your drill with a hole saw. Here are a couple of options:
