jb, I’d introduce the idea of a jointer. 6” width with the longest bed you can find. You’ll never look back.
Also some good pipe clamps.
I think you’ll end up with a skirted design, rather than trestle. the 3/4 thickness just won’t look proportional to that much real estate.
Four pieces will go together nicely to give you 3” square legs, solid.
The leg to apron joints will be the only real joinery challenge, the rest is about straightlining your material and getting good, matching joints.
I, too, will be excited to learn of your progress.
Kindly,
Lee
