6x6 timber beam to cmu wall connection

[Bammer25]

How do you guys typically do this? This is a neighborhood entry sign. I have a simple box 40”x40” cmu structure anchored to a concrete foundation they will add stacked stone to. They want a wooden beam cantilevered out to support a sign.
Doesn’t seem like your typical Simpson wood connectors will handle a moment connection. Possibly set the post into the running bond and build the block around it? Maybe a joist hanger but then have a top steel plate in the mortar bend to get my moment resistance?

Or run it from one side of the cmu square to the other? That may be the most fool proof way. But will I run into issues with the treated wood being in constant contact with the masonry?

Could the cantilever beam be wrapped with polythene where is in contact with masonry?

There are 1 or 2 simpson post bases that can take moment, but typically I'll run the post past whatever I'm attaching to so that I have a bit of a backspan with the cantilever. Similar to a deck railing side connection.

1) For a new build, I'd not want to create the envelope problem that a wood beam penetrating the wall surely would present.

2) A knee brace, top or bottom, has historically been a common way to do this.

3) I'd be tempted to use a steel member wrapped with wood for the sign support. Then, a more conventional steel plate to CMU connection to transfer moment. Or just a steel bracket bolted to the CMU that comes out and grabs the wood beam.

Could you embed an HSS6x6x1/4 in the CMU and use that as the sleeve for the post? Might have to trim it down slightly.

I'd plunge it into the footing or sonotube with like 4' embedment to create something like a moment connection at the bottom. Wrap it with waterproofing tape where it's in contact with concrete or stone. Where it extends out of the stone, flash it to make doubly sure water doesn't drip between the waterproofing sheet. Where it connects at the top to the cantilever, use a knee brace like KootK suggested (great idea), or use stainless steel plates with thru-bolts to make a half-assed moment connection, or extend the post higher and hang the cantilever end with a tension wire, similar to traffic lights.

Maybe a sketch by the OP would get everyone talking about the same thing.

It's an outdoor sign. It's understood that it will be exposed to the elements and will have a limited useful service life and will eventually require replacement. Consider it like a wooden fence. Embed it in the masonry and don't worry about it. Common sense and good practice would suggest to use a naturally durable wood species or pressure treated wood and to use flashing (preferably metal) at the penetration.
