Funny thing is, there's a time where the hot topic is basically facebook eavesdropping conversation then put on ads with item relevant to the conversation. Everyone talk about it being creepy, but everyone keep using it without any change. I think they just don't care ¯\_(ツ)_/¯

A catch-all is not a good idea. But Migadu lets you do something called pattern rewrites which are aliases that can contain wildcards. So you can set up a pattern like shop-*@yourdomain.tld and use addresses like shop-amazon@, shop-etsy@ etc.

It doesn't have to be "shop" you can use anything you want and make up the pattern in any way you want ("ama.shop.zon@" or whatever you can think of).

It's better than plus addresses ("realaddress+amazon@") because it doesn't have to include your real address, and you can make a pattern that nobody can guess, but still retain the ability to use one address per site so you know who's spamming you, and you can make them up on the fly.

In fact I no longer use my "real" address for anything except logging into IMAP and SMTP, I use aliases or patterns for everything else.

Edit: If you want to also be able to send email from these addresses make sure to enable "wildcard sender" for the associated mailbox.

These addresses do have one downside similar to catch-all: if one of them starts getting spam you have to make an explicit deny rule for it. Some people contend that this is a messy approach and they'd rather make regular (non-wildcard) aliases and deny everything else. The downside with that however is that you can no longer make up addresses on the fly, you have to go to the Migadu admin to create the alias every time.
