You haven’t mentioned what type of track your planning to use; nickel silver or steel. I recently started a small end to end EM gauge layout; first time ever building track. First simple point took me a few (!!!) hours but worked beautifully with short wheel-base scratch built wagons.
Using steel track but, regardless of how many say its easy to solder, I wish I had used nickel silver. Doing similar to you as also using PCB sleepers. Thought crossings would be difficult but amazed that with gauges making points is easier that I thought. One thing I have noticed is that regardless of how accurate I am I get both points and plan track tightening up after a few months (any one able to help?).
