[Edit] To the_pwner224's point, you can also create a wildcard and send everything to a catch-all mailbox and/or write rules for it so you can tell a business "their-business-name@yourdomain.tld".

Here are some rules I already have made: https://imgur.com/a/L90sQJD I generate incrementing numbered emails to continue using Glassdoor after they block you for not giving info, thus the glob pattern.
For job seeking, I give employers the email 'job@me.com.' I suppose it does sound a bit weird, but if anyone gets spammy, I can add a rule to delete any messages with to=job@me.com and subject contains company name, without globally blocking any messages with company name in the subject.
FM specifically is based in Australia which you may have issues with, but I've given up trying to maintain privacy vs. big gov - they can see your email regardless of what you use, except maybe ProtonMail.
I also have other custom rules:
filter@[mydomain] goes to a special folder that isn't the inbox, for services whose messages I want to be able to access occasionally, but not most of the time.
spam@[mydomain] goes straight to spam.
I just went through my spam folder and found a bunch of spam (automatically filtered) to my "real" email address. That was surprising until I remembered that my email address is published on my website. I suppose my efforts were somewhat in vain.
