So how will you approach using the bridge conduit? What's your transition? Pull what you need through it to the new panel (short run). Then reel it out to existing panel? What if you nick the insulation jacket installing it? You have burrowing critters nearby? Both spell trouble. Not sure what's allowed, but there is "DB" (direct buried) conduit out there. Thinner than sch 40. I'd explore that option. Maybe someone else will chime in.

Primary closer to service point is best case. But not every best case is practicable. I'm not surprised by the dollar amounts from PG&E and if true, I would choose to use that $$$$$ for the house I'm building.

Not sure whether one 500 MCM conductor has more cross sectional area than two OOOO conductors but if your calculator gives you 3% or less voltage drop (200 amps, 1130 ft. round trip) then the cable you chose will be fine.
