One last (*coughcough) fiddle with the domain names and email and I think I’ve got it. I replaced my professional site with a dead simple one I tossed together with Carrd and redirected jessekelber.com to that.
I already set up a subdomain at micro.jessekelber.com to house this here microblog.
Today I joined Fastmail and have several of my emails including the @jessekelber.com ones going in there.
The next step will be to forward my main Gmail account into Fastmail while using the Takeout system to move my docs into iCloud drive – with the endgoal being deletion of my Google presence at some point in the not-to-distant future.
