Tim,
Congratulations on the move!
And now some “fatherly” advice.
Most guys plan and plan on paper. I did the same thing. Trying to cram as much track into the allotted space. You will be happier in the end with half the track that was first designed on paper.
Most guys I know that put down all that track as they originally planned either removed it as they built, or removed it after they built.
For one thing, maintenance.  You are going to have to get in and clean that track, if you are track powered. (And I assume you will be.)
You have a lot of track to keep level, and a lot of switches to keep debris free.
Access to the layout without stepping on track or other things.
Wire chases, etc.
Tim,
Just saying based on what I’ve experienced and witnessed over the years…
