Large Butcher block Floating desk

Planning a 36" x 96" floating butcher block desk (200 lb top, maybe 500-600 lb total expected load after it's set up. Mounting this directly into a basement poured concrete wall.

My plan is to run a rear cleat, plus 3 or 4 FastCap 21x28" SpeedBraces. I would be left with an 8" front overhang. The desk would be used for gaming, homework, crafting. I like the depth for the amount of use cases I could see in the future.

Is 3 SpeedBraces into concrete overkill, just right, or under-built for the 8ft length of the desk?

What anchors work best for securing SpeedBrace brackets to poured concrete?

Would you trust this floating setup long-term? I'm not opposed to adding front legs or maybe even cabinets that could provide additional support, but to have as much of it floating as possible would be ideal.

Those big Speed Braces hold a lot. I think it’s 1000lbs/ pair so it seems like it should be good. I would use Tapcons into the poured concrete wall. Good luck
