Thank you all for your thoughts and input.
I decided to go the middle of the road approach and ordered the 22 circuit kit from Speedway. In part because it was less cost than Painless and in part because I liked the idea of having extra capacity (over the 12 circuit version) in case I change my mind later about some of the things I currently do not plan to have.
I am sure that doing my own would have worked out just fine and I still may regret not taking that approach but I do not anticipate doing more than one vehicle so the sourcing of all the different wire colors, terminals, etc. seemed like a bigger hassle than I wanted to take on.
I do anticipate mounting the fuse panel on the interior driver's side cowl panel and routing the wire bundles as described above to the front and rear. Braded ground straps are also planned. My battery will be in the standard location (below floor on the right side) making it easy to route positive battery connection to the starter and main ground strap from the battery to the engine block. Given the effort to clean, prime, and paint everything I may run ground wires rather than relying on using the body or frame for ground connections.
