So I had this idea...

All my bolts, hardware, and misc. are in a big box. Everything is tagged,bagged and description.

So many parts!

last thing I want to anticipate is rummaging and searching. Too much valuable time lost.

O.K. A couple of plywood boards side by side and tape all the bags on up so you can see them all hanging?

How did you prepare for re-assemble?
Any method to keeping sanity?

Peg board.

Try organizing into sub assemblies/ areas...rear end, front suspension, engine comp, engine, int, etc. Then focus on one area at a time instead of skipping all over.

Have an assembly strategy, such as:

Set up a spread sheet to organize your numbered bags and numbered boxes.

I organized the spread sheet first by areas of the car: engine bay, front, interior, interior-front, interior-instrument panel, interior-rear, rear, side, trunk, and under. Then by numbers of the chapters of the Service Manual that apply. That is, 01 is Accessories, 02 is Front Suspension, 03 is Rear Axle, 05 is Brakes, etc.

The spreadsheet is put together randomly, then sorted by area then by chapter.

If I want to work on the rear axle and the rear springs, I go to the spreadsheet > Under > 03 Rear Axle and 17 Rear Springs. Here are listed by numbers all the zip lock bags and boxes that apply to these items.

All zip lock bags are stored in trays (actually box lids) and in numerical order. All boxes are stored in numerical order.

I can retreive any bag or box I need quickly.
